Answer:
Option D
Explanation:
When a mixture of n-butyl bromide and ethyl bromide is treated with sodium metal in the presence of dry ether, then ethane cannot be formeds because reaction follows
Wurtz-Fitting reaction . it is a type of coupling reaction.
$CH_{3}CH_{2}CH_{2}CH_{2}Br+CH_{3}CH_{2}Br+2Na $ $\underrightarrow{Dry/ether}$
$C_{4}H_{9}-C_{4}H_{9}+C_{4}H_{9}-C_{2}H_{5}+C_{2}H_{5}-C_{2}H_{5}$
octane Hexane Butane
