Chapter 9: Q9-10 Pb (page 278)

Show the terminal alkyne and alkyl halide from which the following products can be obtained. If two routes look feasible, list both.
$b . {({CH}_{3})}_{2} CHC \equiv {CCH}_{2} {CH}_{3}$

Short Answer

Expert verified

Answer

$b . {({CH}_{3})}_{2} CHC \equiv CH + {CH}_{3} {CH}_{2} Br \to {({CH}_{3})}_{2} CHC \equiv {CCH}_{2} {CH}_{3}$

Step by step solution

Alkylation

Migration of the alkyl group from one molecule to another via carbanion or carbocation formation

Alkylation of acetylide ion

Acetylide ion is a strong nucleophile that reacts with the electrophile like alkyl halide that replaces the halide and forms alkyne. Hence new C-C bond is formed, and the old C-Br bond is broken.
