Consider the following reactions :
`I Me- underset((A))(-=)-Me overset(Na+Liq. NH_(3))underset(EtOH)to (B)`
.
Which statement is wrong about the reactions (i) and (ii) ?

Options

A. The product (B) is trans-but-2-ene and (c) is cis-but-2-ene.
B. The product (B) is cis-but-2-ene and (C) is trans-but-2-ene.
C. The formation of (B) and (c) takes place by anti-and syn-addition of `H_2`, respectively.
D. In the formation of (B), one of the intermediate species is radical anion.

Answer

B

Explanation

b. Reaction (i) proceeds by anti-addition of `H_(2)`. So product (B) is (Trans-But-2-ene).
Reaction (ii) proceeds by syn-addtion of `H_(2)`, so the product (C) is (cis -But-2-ene)
