The correct order of proton accepting tendency is\

Question

Professor PC Thomas Classes · Answer

The proton accepting tendency increases as the basicity of the base increases or acidity of the acid decreases\ $\mathrm{R}-\mathrm{NH}_{2}$ is more basic than $\mathrm{NH}_{3}$\ $\mathrm{H}_{2} \mathrm{~S}$ is a weaker acid than HI\ Thus the correct order is\ $\mathrm{R}-\mathrm{NH}_{2}>\mathrm{NH}_{3}>\mathrm{HS}^{-}>\mathrm{I}^{-}$
