(C) $C{l}_2$	(iii) Pseudohalogen
(D) HF	(iv) $s{p}^3{d}^3$ hybridisation

• A. (A) $\to$ (iv); (B) $\to$(i); (C) $\to$ (iii); (D) $\to$ (ii)
• B. (A) $\to$ (ii); (B) $\to$ (iii); (C) $\to$ (iv); (D) $\to$ (i)
• C. (A) $\to$ (iii); (B) $\to$ (iv); (C) $\to$ (ii); (D) $\to$ (i)
• D. (A) $\to$ (i); (B) $\to$ (ii); (C) $\to$ (iv); (D) $\to$ (iii)

Answer 1

The correct option is C (A) $\to$ (iii); (B) $\to$ (iv); (C) $\to$ (ii); (D) $\to$ (i)

(A) Pseudohalogens are halogens that resembles halogens in their chemistry but are not halogens. Here, $(CN{)}_2$.

(B) $I{F}_7$,

electronic configuration of $I=4d^{10}5s^{2}5p^5$.

(Refer to Image)

(C) $C{l}_2⟶$ Deacon process $⟶$ Process that produces $C{l}_2$ from $HCl$.

(D) $HF⟶$ forms hydrogen bonding due to the highest electronegativity of $F$.
