JEE Main Chemistry question

Decarboxylation of which of the following will yield 1,1,2,2-tetrabromoethane?

(A)CH₃COOH
(B)CHBr₂CBr₂COOHCorrect
(C)CHBr₂COOH
(D)CH₂BrCHBrCOOH

Answer: (B)

Solution

Decarboxylation removes the carboxyl carbon as CO₂ and installs an H on the adjacent (α) carbon in its place. For the two-carbon product CHBr₂–CHBr₂ (1,1,2,2-tetrabromoethane) to result, the three-carbon starting acid's α-carbon (the one directly bonded to –COOH) must already carry two bromines and no H, so that after
