Text Solution

Verified by Experts

The correct Answer is:
B
`C_(2)H_(5)l overset("Alc. KOH")underset(-Hl)rarrunderset("Ethene")underset("(X)")(CH_(2)=CH_(2))overset(Br_(2))rarrunderset("1,2-dibromoethane")underset("(Y)")(BrCH_(2)-CH_(2)Br)overset(KCN)rarr underset("1,2-dicyanoethane")underset("(Z)")(NC CH_(2)-CH_(2)CN)`
