1.

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 rarrProduct

Answer»

a.Statement 1 and Statement 2 are true and Statement 2 is the correct explanation of Statement 1.
b.Statement 1 and Statement 2 are true and Statement 2 is not the correct explanation of Statement 1.
c.Statement 1 is true and statement 2 is false.
d.Statement 1 is false and statement 2 is false

Solution :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 )`.
