Question

By oxidation of which compound carboxylic acid cannot be obtained.
A) 2-Methyl-2-propanol
C 1-Butanol
B) 2-Butanol
D) 3-Propanol​

Answer 1

Answer:

option A)

Explanation:

2 methyl 2 propanol

Answer 2

2-Methyl-2-propanol cannot be oxidized to carboxylic acid.

• 1-Butanol is the primary alcohol that on oxidation produces aldehyde, i.e., butanal. Butanal on further oxidation yields a carboxylic acid, Butanoic acid.
• 2-Butanol is secondary alcohol that on oxidation produces ketone, i.e., butanone. Butanone on further oxidation decomposes to give carboxylic acids.
• In propanol, the third and first carbons are equivalent. 3-Propanol is primary alcohol that on oxidation produces aldehyde, i.e., propanal. Propanal on further oxidation form carboxylic acid, propanoic acid.
• 2-Methyl-2-propanol is a tertiary alcohol and decomposes on oxidation.
