In 9.13, if the alkoxy oxygen atom was protonated instead, would we get an alcohol (ROH) and the starting hemiacetal? How do we know which O will be protonated, that of the alkoxy group or the hydroxyl’s? Any help is greatly appreciated!! Thanks a lot in advance :~)
As I understand it, both dehydration of alcohols and their reactions with alkyl halides require a strong acid for the protonation of the hydroxyl group to turn it into a good leaving group (water). Does this not mean all of these reactions are acid-catalyzed?
My textbook only mentions “acid catalyst” when talking about reactions of 1° alcohols with hydrogen halides. It says that it requires a mixture of concentrated hydrochloric acid and a Lewis acid as a catalyst like zinc chloride to form an alkyl chloride. Any help is greatly appreciated!
Is it possible to replace hydroxyl groups with hydrogen in acids via reduction or other means?
In synthesis of aspirin, why does H+ attack the carbonyl group of the anhydride instead of the hydroxyl group of salicylic acid?
Isn’t this supposed to be 2,4,6-trimethylphenol instead since the hydroxyl group takes the number 1?
Why does my textbook say that alkenes are a functional group? I thought they were a family of organic compounds. The textbook also says that alcohols are a functional group. Shouldn’t hydroxyl be the functional group of alcohols? TIA!

In peptide bond formation, does amino group react with carboxyl or hydroxyl?
A practice problem asks what functional group an amino group reacts with when forming a peptide bond. It says that carboxyl group is correct, and hydroxyl group is incorrect. But hydroxyl is part of carboxyl, and the hydroxyl is the part of the carboxyl that the amino group reacts with when forming a peptide bond. What am I missing here?
When you’ve been studying too long, forget it’s Christmas, and wonder why there’s a hydroxyl group on your towel...
Hi guys, I’m sorry if this is a stupid question. I don’t understand what happens to the hydroxyl group bonded to carbon 3 in the sugar when it forms a phosphodiester bond ..?
MRW I'm irrationally terrified of hydroxyl groups and I get put in the psych ward and the doctor asks what's been bugging me
Is hydroxyl the functional group in this diagram ?
Are aromatic hydroxyl groups better reducing agents than other hydroxyl groups?
Are aromatic hydroxyl groups better reducing agents than other hydroxyl groups?
I’ve been reading that chemicals that are antimicrobial often have aromatic hydroxyl groups that make them better reducing agents. Does anyone know why that makes them better reducing agents? Also, why does being a good reducing agent make a compound antimicrobial?
introducing an amino group at the highlighted hydroxyl position
I have an idea of what to do, but would like to see if there are any other methods to substituting a amino group for the highlighted hydroxyl.

How does the position of the hydroxyl group affect the enthalpy of combustion?
Why does pentan-3-ol have a lower enthalpy of combustion compared to pentan-1-ol?
Is this MileDown card correct (Beta dicarb acids): Kaplan is telling me it is the hydroxyl group
[High School Biochemistry] What would be the product of this reaction? I know it's a phosphodiester bond but don't know how to do it with ions. I've done it with the two hydroxyl group and then getting water but here it's an ion.

why can't a hydroxyl group transfer its hydrogen atom?
Hi!
I was working on a task on citric acid where you had to explain why there would be three graphs on its Bjerrum plot. I explained that since citric acid contains three carboxylic acid groups, it could transfer a hydron three times from each carboxylic acid group and therefore create three different graphs on a Bjerrum plot. My question then arose when i saw that citric acid also contains hydroxyl group, and i was wondering why the hydrogen atom from this group could't be transferred.
Thanks in advance! (sorry if its not correctly phrased, english isn't my native language)
What hydroxyl group gets protonated? Does this produce a cyclic amide or is this one of those exceptions that kick out a bad leaving group due to a high-energy intermediate (like the LiAlH4 reduction of carboxylic acids)? Thanks!
ACS help: Can someone please what the hemiacetal intermediate would look like and where the hydroxyl group of the hemiacetal that gets protonated to form water?
How do I know which carbon will take the hydrogen and which will take the hydroxyl group if the alkene (2-butene) is symmetrical?

I cannot decide between C and E.
I am learning towards C, but I can't seem to rule out C because I looked up hydroxyl groups and saw that it was R-OH and couldn't R be anything which would satisfy the rest of the chain in the image?
I’m a hydroxyl group and you’re a nitrogen, let’s make a hydrogen bond
Why do some nucleotides have a phosphate group with hydroxyl attached while others have oxygen
I was recently looking into the dehydration synthesis of nucleotides and how that creates nucleic acid, and I’m confused as to how one of the nucleotides must have a phosphate group with a hydroxyl attached in order for this to work.
To my understanding, it’s “normal” for the phosphate to have four oxygen attached and then the R group, but I’ve come across some with two hydroxyl and two oxygen instead (in addition to the R group).
Can anyone tell me why this is the case? Are there multiple types of phosphate groups? Do the phosphates in nucleotides vary in structure?
Thanks for any help
When you protonate a hydroxyl group to make it a better leaving group.
Saw this tattoo online someone got! I’m working on figuring out the IUPAC name for it. I know there’s a ketone, hydroxyl group and it’s a polycyclic aromatic but struggling to get a name. Any help?
[Organic Chemistry] Fundamental question about hydroxyl groups and how they relate to alcohol
Alcohols are commonly identified by their -OH hydroxyl group. However, what is the proper nomenclature when it is part of a compound? Surely not every compound with a hydroxyl group is an alcohol. But, is the hydroxyl group itself considered an alcohol? Or is it considered just a hydroxyl group? Basically, when would you consider the -OH to be an alcohol compared to just being a plain ol' hydroxyl group? Does it have to do with whether or not it forms aldehyde when it is oxidized?
Why is the chlorine planar and not Trans with the hydroxyl group?
Imagine the substrate for an enzyme contains a hydroxyl group. If present in the binding site on the enzyme, which amino acid's side chain could assist in binding the substrate to the enzyme by forming a hydrogen bond with the hydroxyl group on the substrate?
A/ Isoleucine
B/ Glycine
C/ Threonine
D/ Valine
