Name the ester obtained when the alcohol is reacted with 2-ethylpentanoic acid?
1. 2 -propanol
2. 2-butanol
3, phenol
1.) 4-methylbutyl 3-ethylpentanoate
2.) 2-methylethyl 3-ethylpentanoate
3.) Phenol 3-ethylpentanoate
Replace the 3's with 2's. Did it again.
1.) 2-methylethyl 2-ethylpentanoate
2.) 3-methylpropyl 2-ethylpentanoate
3.) Phenol 3-ethylpentanoate
3.) Phenol 2-ethylpentanoate
Sorry about that one.
Ok I understand how your getting the parent compound. I'm not understanding where for example question 1, the '2-methylbutyl'. That's where I keep getting messed up.
Your going to count the number of carbons from the end furthest away from the ester. So, lets take 2 propanol for example:
O-and everything else
I
CH3-CH-CH3
1---2----methyl
Hope that makes since. Spacing is a problem on this forum.
O-and everything else
I
should be connected to the CH
Oh ok thank you. Sorry, I'm really dumb when it comes to this stuff
:)
To determine the ester obtained when the alcohol reacts with 2-ethylpentanoic acid, we need to understand the process of esterification.
Esterification is a chemical reaction between an alcohol and a carboxylic acid, resulting in the formation of an ester and water. In this case, the alcohol is being reacted with 2-ethylpentanoic acid.
The key to figuring out the ester product is to look at the alcohol reactant. In this case, the options provided are:
1. 2-propanol
2. 2-butanol
3. phenol
To identify the ester, we need to combine the alcohol with the acid. The alcohol will lose its -OH (hydroxyl) group, while the acid will lose its -COOH (carboxyl) group.
In the case of 2-propanol, the resulting ester would have the of the general form R-COO-R', where R and R' represent the alkyl groups. Since 2-propanol has a propyl group, the ester would be propyl pentanoate.
For 2-butanol, the resulting ester would be butyl pentanoate.
However, in the case of phenol, it does not have an -OH group in the form of an alcohol. Therefore, it cannot participate in esterification reactions. As a result, phenol will not react with 2-ethylpentanoic acid to form an ester.
Therefore, the correct answer would be option 2: 2-butanol.
