Vedclass · Answer

(C) Steric inhibition of resonance $(SIR)$ occurs when bulky groups at the ortho positions of a substituent force the substituent out of the plane of the benzene ring,thereby disrupting conjugation.In $1$-bromo-$2,4,6$-trinitrobenzene,the bulky nitro groups at the ortho positions ($2$ and $6$) with respect to the bromine atom force the nitro groups out of the plane of the benzene ring,inhibiting resonance between the nitro groups and the ring. This is a classic example of steric inhibition of resonance.

Identify the compound in which steric inhibition of resonance is present.
