On the basis of E.N. difference of \( \left|X_{O}-X_{E}\right| \) and \( \mid \) \( \mathrm{X}_{\mathrm{O}}-\mathrm{X}_{\mathrm{H}} \mid \), acidic and basic characters of \( \mathrm{E}-\mathrm{O}-\mathrm{H} \) can be decided, and acidic and basic strengths are compared.
Correct order of acidic strength is:
(a) \( \mathrm{Na}-\mathrm{O}-\mathrm{H}\mathrm{K}-\mathrm{O}-\mathrm{H}\mathrm{Rb}-\mathrm{O}-\mathrm{H} \)
(b) \( \mathrm{Na}-\mathrm{O}-\mathrm{H}\mathrm{K}-\mathrm{O}-\mathrm{H}\mathrm{Li}-\mathrm{O}-\mathrm{H} \)
(c) \( \mathrm{H}-\mathrm{O}-\mathrm{K}\mathrm{H}-\mathrm{O}-\mathrm{Rb}\mathrm{Na}-\mathrm{O}-\mathrm{H} \)
(d) None of these
