A)Steric and electronic
B)Inductive and steric
C)Inductive and resonance
D)Resonance and electronic

Question

Quizplus · Accepted Answer

The two effects that have to be considered to determine the influence a substituent will have on electrophilic aromatic substitution are the inductive effect and the resonance effect. Inductive effect refers to the withdrawal or donation of electron density through sigma bonds, while resonance effect refers to the delocalization of electrons through pi bonds. Option A is incorrect because steric effect refers to the physical hindrance caused by the size of a substituent and not its electronic influence. Option B is incorrect because while inductive effect is one of the effects that must be considered, steric effect is not. Option D is incorrect because resonance effect is one of the effects that must be considered, but electronic effect is not specific enough as it encompasses both inductive and resonance effects.
