To synthesize the unsymmetrical alkyne `CH_3-C-=C-CH_2-CH_3` the reagents needed would be

A

Ethene, iodoethane, iodomethane and potassium hydroxide

B

Acetaldehyde, 1-bromopropane and conc. `H_(2)SO_(4)`

C

1, 2-dichloroethane, 1-propanol and alcoholic potassium hydroxide

D

Ethyne, iodomethane, iodoethane and sodamide

Text Solution

Verified by Experts

The correct Answer is:
D
`CH-=CH overset(NaNH_2)rarr CH -=C^(-)Na^(+) overset(CH_3I)underset(-NaI)rarrCH-=CH-CH_(3)`
`underset("Pent-2-yne")(C_(2)H_(5)-C-=C-CH_(3)) overset(C_2H_5I)underset(-Nal)larr Na^(+)C^(-)-=C-CH_3`
