Vedclass · Answer

(A) The inductive effect ($+I$ effect) is the permanent displacement of sigma electrons towards a more electropositive group or atom.Among the given options,the negatively charged oxygen atom $(-\mathop O\limits^\Theta)$ has the highest electron density and is the most electron-donating group.The order of $+I$ effect strength is: $-\mathop O\limits^\Theta > -CH_2-CH_3 > -CH_3 > -CD_3$.Therefore,the correct option is $A$.

Which of the following has the strongest $+I$ effect?
