Question

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.

Choose the correct option.

• A. A and R both are correct and R is the correct explanation of A
• B. A and R both are correct, and R is not the correct explanation of A
• C. A is true, but R is false
• D. A and R both are false

Answer 1

The correct option is A

A and R both are correct and R is the correct explanation of A

Assertion and reason both are correct and reason is the correct explanation of assertion,

$\underset{(2,81)}{Na}+\underset{(2,8,7)}{Cl}\to \underset{\underset{(2,8,8)}{(2,8)}}{NaCl}$

Here both $N{a}^{+}\text{and}C{l}^{-}$ have complete octet hence NaCl is stable.
