In ${\rm{H}}{{\rm{S}}^ - },{{\rm{I}}^ - },{\rm{R}} - {\rm{N}}{{\rm{H}}_2},{\rm{N}}{{\rm{H}}_3}$ order of proton accepting tendency will be:

$R{\rm{N}}{{\rm{H}}_2} > N{{\rm{H}}_3} > H{{\rm{S}}^ - } > {{\rm{I}}^ - }$

${{\rm{I}}^ - } > N{{\rm{H}}_3} > R{\rm{N}}{{\rm{H}}_2} > {\rm{H}}{{\rm{S}}^ - }$

${\rm{N}}{{\rm{H}}_3} > R{\rm{N}}{{\rm{H}}_2} > H{{\rm{S}}^ - } > {{\rm{I}}^ - }$

${\rm{H}}{{\rm{S}}^ - } > R{\rm{N}}{{\rm{H}}_2} > N{{\rm{H}}_3} > {{\rm{I}}^ - }$

order of proton accepting tendency will be:

View answer and explanation

Correct option: C

R\mathrm{N}{\mathrm{H}_2} > N{\mathrm{H}_3} > H{\mathrm{S}^ - } > {\mathrm{I}^ - }

Option C is correct. Alkyl amines are more basic than ammonia due to the +I effect of the alkyl group. HS- is more basic than I- because S is more electronegative than I.
