Show Answer
Answer:
Correct Answer: 25. ( b,c )
Solution:
(a) Number of $\mathrm{Cl}^-=\mathrm{O}$ bonds in (ii) and (iii) together is three. Hence, wrong.
(b) Number of Lone Pair on $\mathrm{Cl}$ in (ii) and (iii) together is three. Hence, correct.
(c) In (iv), $\mathrm{Cl}$ is $s p^3$-hybridised. Hence, correct.
(d) Amongst (i) to (iv), the strongest acid is (iv). Hence, wrong.
