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...)

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"?

3. The hydrogen atom in a carboxyl group is an [acidic] hydrogen.
I had no ideas what the statement is talking about....

Thanks in advance!

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.

I would leave it as is.

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.

1. The ester formed from formic acid and methanol is called methyl formate. To determine the name, you are correct in using the ending "-oate" for the ester part. In this case, we replace the "-oic acid" ending of formic acid (HCOOH) with "-oate," while keeping the prefix of the alcohol intact. So, methanol (CH3OH) remains as methyl in the ester name.

2. The statement is incorrect. The correct statement is: "The carboxyl end of a carboxylic acid is electron-deficient." The carboxyl group (-COOH) consists of a carbonyl group (C=O) and a hydroxyl group (OH). The carbonyl carbon in the carboxyl group is electron-deficient, meaning it lacks electron density and is more prone to release a proton, making it acidic. Therefore, the carboxyl end of a carboxylic acid is electron-deficient.

3. The statement is correct. The hydrogen atom attached to the carboxyl group (COOH) is an acidic hydrogen. This means it can easily dissociate from the compound in the presence of a base to form a carboxylate ion (COO-) and a proton (H+). This acidity is due to the electron-withdrawing nature of the carbonyl group, which makes the hydrogen atom more prone to losing its proton.
