Answer 1

Answer #1

So a strong base is one which completely gets ionises in solution and weak bases are those which partially ionises in solution . As we also know that a base accepts H⁺ ion , so in this question also pyridine being a weak base will accept H⁺ from water .

Pyridine has ring structure in which N is sp² hybridised , and also there is lone pair present on N so s - character is more as well as lone pair is present. So this makes pyridine less likely to accept H⁺ from water .

Equation of pyridine ionization in water : -

C₅H₅N ( aq.) + H₂O ( l) $\rightleftharpoons$ C₅H₅NH⁺ (aq.) + OH^- (aq.)
