The number of primary isomeric alcohols of the molecular formula C ₄ H ₁₀ O is

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

B. 2

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. A
