Dihalides in which two halogen atoms are attached to two adjacent carbon atoms are known as vicinal dihalides. On reaction with

Z n

, these form alkene by losing a molecule of

Z n X_{2}

as shown below :

1,2-dibromo propane C H_{3} C H B r - C H_{2} B r + Z n ⟶ propene C H_{3} C H == C H_{2} + Z n B r_{2}

Q. The product $(X)$ obtained in the following reaction is
$C H_{3} C H B r - C H_{2} B r + Z n ⟶^{'} X^{'}$

$C H_{3} C H_{2} - B r ∣ C H_{2}$

$C H_{3} B r ∣ C H - C H_{3}$

$C H_{3} C H == C H_{2}$

None of these
