Question

Which is the most resistant alcohol towards oxidation reaction among the following

Answer 1

Tertiary alcohols (R3COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms.

Answer 2

The whole question is as follows:

Which is the most resistant alcohol towards oxidation reaction among the following

A) CH3−CH2−OH

B) (CH3)2−CH−OH

C) (CH3)3−C−OH

D) C2H5-CH (CH3)- OH

Answer:

Option (C) (CH3)3-C-OH is the correct answer.

Explanation:

Why Tertiary alcohol [(CH3)3-C-OH] is the most resistant alcohol towards oxidation reaction?

• In Tertiary alcohol, -OH group is attached to the carbon which have no hydrogen atom to bond with during oxidation process.
• While in primary and secondary alcohol, -OH group is attached to the carbon atom which has 2 and 1 hydrogen atoms respectively attached with carbon.
• So, Primary and Secondary alcohol can easily undergo oxidation reaction.
• And Tertiary alcohol is the most resistant towards oxidation reaction.
