On reaction with sodium, 1 mol of a compound X gives 1 mol of H 2. Which one of the following compounds might be X ?

Question

On reaction with sodium, 1 mol of a compound X gives 1 mol of H 2. Which one of the following compounds might be X ? (A) CH 3 CH 2 CH = CH 2 (B) CH 3 COOCH 2 CH 3 (C) CH 3 CH 2 CH 2 OH (D) CH 2( OH 2) CH 2 CH 2 CH 2 OH

Since 1 mole of compound X reacts with Na to evolve 1 mole of H2 gas, therefore the compound should have 2 active hydrogen atoms per mole which is possible only in option d. CH 2 OHCH 2 CH 2 CH 2 OH +2 Na arrow NaOCH 2 CH 2 CH 2 CH 2 ONa +2 H

Q. On reaction with sodium, $1 m o l$ of a compound $X$ gives $1 m o l$ of $H_{2}$ . Which one of the following compounds might be $X$ ?

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

$C H_{3} COOC H_{2} C H_{3}$

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

$C H_{2} (O H^{2}) C H_{2} C H_{2} C H_{2} O H$

Since $1$ mole of compound $X$ reacts with $N a$ to evolve $1$ mole of $H_{2}$ gas,
therefore the compound should have $2$ active hydrogen atoms per mole which is possible only in option $d$ .
$C H_{2} O H C H_{2} C H_{2} C H_{2} O H + 2 N a \to N a OC H_{2} C H_{2} C H_{2} C H_{2} ON a + 2 H$

Q. On reaction with sodium, 1mol of a compound X gives 1mol of H2​. Which one of the following compounds might be X ?
