Question

which among the following is not obtained when ethyl chloride and n-propyl chloride undergoes wurtz reaction ?

• A. n–butane
• B. n–pentane
• C. n–hexane
• D. isobutane

Answer 1

The correct option is D isobutane

Wurtz reaction between ethyl chloride and n-propyl chloride
$\underset{\text{ethyl chloride}}{C_2{H}_5-Cl}+\underset{\text{n-propyl chloride}}{C_3{H}_7-Cl}+2Na\stackrel{\text{dry ether}}{\to }\underset{\text{n-butane}}{C_2{H}_5-C_2{H}_5}+\underset{\text{n-hexane}}{C_3{H}_7-C_3{H}_7}+\underset{\text{n-pentane}}{C_2{H}_5-C_3{H}_7}$
