Question:medium

The molecule with a maximum boiling point is

Show Hint

Hydrogen bonding raises the boiling point most, and a diol has two OH groups.

  • \(\text{CH}_3-\text{CH}(\text{OH})-\text{CH}_2-\text{CH}_2-\text{OH}\)
  • \(\text{CH}_3-\text{CH}_2-\text{Br}\)
  • \(\text{CH}_3-\text{CH}_2-\text{CH}_2-\text{Br}\)
  • \(\text{CH}_3-\text{C}(\text{CH}_3)(\text{Cl})-\text{OH}\)
Show Solution

The Correct Option is A

Solution and Explanation

Step 1: Rank
Roughly: bromoethane $38^{\circ}$C, bromopropane $71^{\circ}$C, butane-1,3-diol about $207^{\circ}$C. The diol is clearly highest. Option (A).

Final Answer:
Option (A). \[ \boxed{\text{(A)}} \]
