MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The molecular formula C _4 H _ 10 O represents saturated acyclic alcohols and ethers. Primary alcohols have the general formula R - CH _2- OH . For C _4 H _ 10 O , the alkyl group R must be a propyl group ( C _3 H _7). There are two isomeric propyl groups: 1. n-propyl group: - CH _2 CH _2 CH _3 2. isopropyl group: - CH ( CH _3)_2 Attaching these to the - CH _2 OH group gives two primary alcohols: 1. CH _3 CH _2 CH _2 CH _2 OH (Butan-1-ol) 2. CH _3 CH ( CH _3) CH _2 OH (2-Methylpropan-1-ol) Thus, there are 2 primary isomeric alcohols. Answer: 2
