Question

Assertion (A): $N_3-$ is isostructural with $I_3{}^{-}$
Reason(R) : The E.N of $N$ is greater than $I$

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
• C. (A) is true and (R) is false
• D. (A) is false but (R) is true

Answer 1

Answer: (B)

Both (A) and (R) are true and (R) is not the correct explanation of (A)

$N_3{}^{-}$ structure is linear and $spN$

$I_3{}^{-}$ geometry is trigonal bipyramidal and three lone pair of electrons.

Therefore, the shape is linear and $s{p}^{3}dI$

The assertion is true and $N$ has a higher electronegativity than $I$ but they are not related.
