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

Answer»

Ethene, iodoethane, IODOMETHANE and potassium hydroxide
Acetaldehyde , 1-bromopropane and conc. `H_2SO_4`
1,2-dichloroethane , 1-propanol and ALCOHOLIC potassium hydroxide
Ethyne, iodomethane , iodoethane and sodamide

Solution :`CH-=Choverset(NaNH_2)to CH-=C^(-)NA^(+) UNDERSET"-NAI"overset(CH_3I)to CH-=C-CH_3`
`underset"Pent-2-yne"(C_2H_5-C-=C-CH_3)underset"-NaI"overset(C_2H_5I)larr Na^(+)C^(-) -=C-CH_3`
