Question

Statement 1: The product formed is (B).
Statement 2: The reaction proceeds via the formation of the following species in the order: Radical anion `rarr` Vinylic anion `rarr` Vinylic redical `rarr` Product
A. a.Statement 1 and Statement 2 are true and Statement 2 is the correct explanation of Statement 1.
B. b.Statement 1 and Statement 2 are true and Statement 2 is not the correct explanation of Statement 1.
C. c.Statement 1 is true and statement 2 is false.
D. d.Statement 1 is false and statement 2 is false

Answer 1

Correct Answer - C
The reduction of `(C-=C)` to `(C=C)` takes place by anti-addition of hydrogen with `(Na+ liq. NH_(3) + EtOH)`, so the product formed is `(B)`. Statement `1` is true. But statement `2` is false, since the mechanism of the reaction proceeds as follows.
Radical anion `rarr` Vinylic redical `rarr` Vinylic anion rarr product.
Statement `1` is true and statement `2` is false. So the answer is `(c )`.
