Chemistry - GOC Question with Solution | TestHub

Solution:

BASIC STRENGTH $\left[{\mathrm{k}}_{\mathrm{b}}\right]\propto +\mathrm{M}$ effect

$\propto +I$ effect

(i)

→ It is most Basic compound in organic chemistry.

⟶ After protonation it forms 3 equivalent Resonating structure.

(ii)

→ It is 2nd most strongest Base of organic chemistry

→ After protonation it forms 2 equivalent Resonating structure.

(iii)

∴ order of ${\mathrm{k}}_{\mathrm{b}}$ is: $\mathrm{i}>$ ii $>$ iii

Hence, Correct option: (A)
