Question

Which of the following compounds will give a racemic mixture on nucleophilic substitution by OH ion?

1-Bromoethane, 1-Bromopropane, 1-Bromobutane, Bromobenzene

Options

• Bromobenzene < 1-Bromobutane < 1-Bromopropane < 1-Bromoethane

• Bromobenzene < 1-Bromoethane < 1-Bromopropane < 1-Bromobutane

• 1-Bromopropane < 1-Bromobutane < 1-Bromoethane < Bromobenzene

• 1-Bromoethane < 1-Bromopropane < 1-Bromobutane < Bromobenzene

Answer 1

1-Bromoethane < 1-Bromopropane < 1-Bromobutane < Bromobenzene

Explanation:

Higher the molecular weight, higher will be the boiling point.
