Question

Molecular formula of sodium hydride is ____.

• A. $\text{Na}{\text{H}}_{\text{3}}$
• B. $\text{N}{\text{a}}_{\text{2}}{\text{H}}_2$
• C. $\text{Na}\text{H}$
• D. $\text{N}{\text{a}}_{\text{2}}\text{H}$

Answer 1

Answer: (C)

$\text{Na}\text{H}$

Sodium hydride is the chemical compound with the empirical formula NaH. This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis

Sodium ion has +ve charge and hydride ion has -ve charge , so the molecular formula will be NaH.
