NEET Haloalkanes and Haloarenes — Set 15

Question 1

What is the product when benzene reacts with $ \ce{CH3CH2Cl} $ in the presence of $ \ce{AlCl3} $?

Accepted Answer

This is a Friedel-Crafts alkylation. Benzene reacts with $ \ce{CH3CH2Cl} $ and $ \ce{AlCl3} $ to form $ \ce{C6H5CH2CH3} $ (ethylbenzene).

Question 2

Which reagent converts 1-butanol to 1-chlorobutane with gaseous byproducts?

Accepted Answer

$ \ce{SOCl2} $ reacts with 1-butanol ($ \ce{CH3CH2CH2CH2OH} $) to form 1-chlorobutane ($ \ce{CH3CH2CH2CH2Cl} $), producing $ \ce{SO2} $ and $ \ce{HCl} $ gases.

Question 3

Which halide reacts with $ \ce{Na} $ in dry ether to form $ \ce{CH3CH2CH2CH2CH2CH3} $ as the sole product?

Accepted Answer

Wurtz reaction of $ \ce{CH3CH2CH2Cl} $ (1-chloropropane) couples to form hexane ($ \ce{CH3CH2CH2CH2CH2CH3} $).
