What will be the decreasing order of basic strength of the following conjugate bases? \(^ - {\rm{OH}},{\rm{R}}{{\rm{O}}^ - },{\rm{C}}{{\rm{H}}_{\rm{3}}}{\rm{CO}}{{\rm{O}}^ - },{\rm{C}}{{\rm{l}}^ - }\)
Conjugate bases of weaker acids are stronger. Acidic strength order : \({\mathrm{\mathrm{HCl}>\mathrm{CH}_{3} \mathrm{COOH}>\mathrm{H}_{2} \mathrm{O}>\mathrm{ROH}}}\) Basic strength order : \({\mathrm{\mathrm{Cl}^{-} < \mathrm{CH}_{3} \mathrm{COO}^{-} < { }^{-} \mathrm{OH} < \mathrm{RO}^{-}}}\) So, the correct option is (1).

Correct order of \(\mathrm{K}_{\mathrm{a}}\) in the following compounds is
1 IV \(>\) I \(>\) II \(>\) III
2 III \(>\) IV \(>\) I \(>\) II
3 II \(>\) I \(>\) IV \(>\) III
4 IV \(>\) III \(>\) II \(>\) I
Explanation:
EWG like \(-\mathrm{NO}_{2}, \mathrm{Cl}\) increases acidic strength. -I groups at closer distances increases acidic strength. Acidity or Acidic strength \(\alpha \mathrm{K}_{\mathrm{a}} \alpha \dfrac{1}{\mathrm{pK}_{\mathrm{a}}}\) So, correct order is II > I > IV > III.

Which of the following is correct regarding the strength of (-I) effect of the substituents?
1 \({\rm{ - N}}{{\rm{R}}_{\rm{2}}}{\rm{ < - OR < - F}}\)
2 \({\rm{ - N}}{{\rm{R}}_{\rm{2}}}{\rm{ > - OR < - F}}\)
3 \({\rm{ - N}}{{\rm{R}}_{\rm{2}}}{\rm{ < - OR > - F}}\)
4 \({\rm{ - N}}{{\rm{R}}_{\rm{2}}}{\rm{ > - OR > - F}}\)
Explanation:
Greater the electronegativity, higher is the - I effect. Thus \(-\mathrm{F}>-\mathrm{OR}>-\mathrm{NR}_{2}\).
