JEE Main 2024 Chemistry question

Chemistry Hydrocarbons JEE Main 2024

Compound A formed in the following reaction reacts with B gives the product C. Find out A and B. CH₃–C≡CH + Na → A →(B) CH₃–C≡C–CH₂–CH₂–CH₃ (C) + NaBr

(A)A = CH₃–C≡C⁻Na⁺, B = CH₃–CH₂–CH₂–BrCorrect
(B)A = CH₃–C≡C⁻Na⁺, B = CH₃–CH₂–CH₃
(C)A = CH₃–CH₂–CH₃, B = CH₃–C≡CH
(D)A = CH₃–CH=CH₂, B = CH₃–CH₂–CH₂–Br

Answer: (A)

Solution

Propyne with Na gives the sodium acetylide CH₃–C≡C⁻Na⁺ (A), which reacts with
