Question

One of the iosmers of $C_4{H}_{9}Cl$ by Wurtz reaction forms $2,2,3,3$- tetramethylbutane. The structure of that isomer of $C_4{H}_{9}Cl$:

• A. $1$-Chloro - $2$- methylpropane
• B. $2$-Chloro - $2$- methylpropane
• C. $2$-Chloro butane
• D. $1$-Chlorobutane

Answer 1

The correct option is B $2$-Chloro - $2$- methylpropane

Wurtz reaction: In this process alkyl halide forms alkane in presence of sodium and dry ether.
Reaction:
$C{H}_{3}C\left(C{H}_3\right)ClC{H}_3+2Na+C{H}_{3}C\left(C{H}_3\right)ClC{H}_3\to C{H}_{3}C\left(C{H}_3{)}_{2}C\right(C{H}_3{)}_{2}C{H}_3$
$2$-Chloro - $2$- methylpropane is the answer.
