1. What is the name of the ester formed from formic acid and methanol?
( I know formic acid equals methanoic acid(HCOOH) and we need to change "oic acid" to "-oate", but how about methanol? I had no ideas what to do with the alcohol...)
The alcohol part is named first and the acid part named last. So the alcohol is CH3OH and that is methyl. The last part is methanoate.
Do the words in brackets suit the statements below? If not, correct it.
2. The [carboxyl] end of a carboxylic acid is electron rich.
Is it wrong? Should I change it to "hydroxyl"?
I would leave it as is.
3. The hydrogen atom in a carboxyl group is an [acidic] hydrogen.
I had no ideas what the statement is talking about....
Carboxylic acids are RCOOH and the H on the COOH part is acidic. Methanoic acid, ethanoic acid, propanoic acid etc. ALL have the terminal COOH group on them. (and all of them are acidic).
For the first one, isn't CH3 methyl? Why is CH3OH also methyl?
So the statements of the second and the third one are true...?
Also, can you give me some good links that talks about the properties of carboxylic acids and esters with good explanations?
Thanks.
You misread my response or I misrepresented it---one or the other. Yes, CH3OH is methyl alcohol (the trivial name) or methanol if you name it by the IUPAC system. CH3- is the methyl group> The first part of the name is methyl because
1. its the alcohol (from CH3OH)
2. CH3- is the methyl group
I have tried to post sites but the board isn't posting.
