Question

Which of the following haloalkanes reacts with aqueous $KOH$ most easily?

• A. 1-Bromobutane
• B. 2-Bromobutane
• C. 2-Bromo-2-methylpropane
• D. 2-Chlorobutane

Answer 1

Answer: (C)

The tertiary carbocation formed in the reaction is stable in 2-Bromo-2-methylpropane. So these haloalkanes react with aqueous KOH most easily.
