The molecule with a maximum boiling point is

Options

  1. ACH ₃ - CH ( OH ) - CH ₂ - CH ₂ - OH
  2. BCH ₃ - CH ₂ - Br
  3. CCH ₃ - CH ₂ - CH ₂ - Br
  4. DCH ₃ - C ( CH ₃)( Cl ) - OH

Correct answer

A. CH ₃ - CH ( OH ) - CH ₂ - CH ₂ - OH

Step-by-step solution

The boiling point of a compound depends on the strength of its intermolecular forces. Molecules containing - OH groups can form intermolecular hydrogen bonds, which are significantly stronger than the dipole-dipole interactions and London dispersion forces present in alkyl halides. Therefore, alcohols generally have higher boiling points than alkyl halides of comparable molecular mass. Among the given options: CH ₃ - CH ₂ - Br and CH ₃ - CH ₂ - CH ₂ - Br are alkyl halides and do not exhibit hydrogen bonding. CH ₃ -
