Q. Diethyl ether can be distinguished from $n$ -butanol by
(1) aqueous $F e C l_{3}$
(2) reaction with Na metal
(3) Tollens' reagent
(4) reaction with chromic anhydride $(C r O_{3})$ in dil. $H_{2} S O_{4}$

1, 2 and 3 are correct

1 and 2 are correct

2 and 4 are correct

1 and 3 are correct

$C H_{3} C H_{2} C H_{2} C H_{2} O H + N a ⟶ C H_{3} C H_{2} C H_{2} C H_{2} O - N a + + H_{2}$
$C H_{3} C H_{2} OC H_{2} C H_{3} + N a ⟶$ no reaction
$C H_{3} C H_{2} C H_{2} C H_{2} O H C r O_{3} + dil H_{2} S O_{4}$
$C H_{3} C H_{2} C H_{2} C H O [O] C H_{3} C H_{2} C H_{2} COO H$
