Reaction of compound A (molecular formula = C₇H₁₂) with sodium amide, followed by reaction with 1-bromobutane produces a compound with a structure of (CH₃)₂CHCH(CH₃)CC(CH₂)₃CH₃. What is the name of compound A? A) 2,3-dimethylnon-4-yne B) 2,2-dimethylpent-1-yne C) 3,4-dimethylpent-1-yne D) 4,4-dimethylhept-1-yne E) 1-heptyne

Question

Quizplus · Accepted Answer

Compound A has the molecular formula of C2H2S2C6H12S2 and can be simplified as C4H4S4C12H24S4. The reaction with sodium amide, followed by 1-bromobutane, introduces a 5-carbon chain with an alkyne and alkene functional group. Therefore, the final structure should have 6 carbons in the chain. Only option C has a 6-carbon chain with two substituents and one alkyne at the first carbon from the end, which matches the given compound.
