Assertion $(A)$ : Sodium chloride formed by the action of chlorine gas on sodium metal is a stable compound.
Reason $(R)$ : This is because sodium and chloride ions acquire octet in sodium chloride formation.
  • ✓
    $A$ and $R$ both are correct, and $R$ is the correct explanation of $A.$
  • B
    $A$ and $R$ both are correct, but $R$ is not the correct explanation of $A$.

Answer

Correct option: A.
$A$ and $R$ both are correct, and $R$ is the correct explanation of $A.$
Sodium chloride $\left(\mathrm{Na}^{+} \mathrm{Cl}^{-}\right)$ is stable ionic compound because both $\mathrm{Na}^{+}$and $\mathrm{Cl}^{-}$ ions have complete octate in outermost shell.
