STERIC INHIBITION OF RESONANCE-EXAMPLE 3

(A) With HI, anisole forms iodobenzene and methyl alcohol. (R ) I^(-) ion will combine with smaller group to avoid steric hindrance.

Statement -I: (CH_(3))_(2)CHCHO mainly undergoes Cannizzare reaction when heated with strong alkali. Statement-II:Steric hindrance prevents aldol condensation.

Statement-I, underset("Major product")(Me-overset(OH)overset(|)(C)H-underset(Br)underset(|)(C)H-Et) Statement-II: Me exert less steric hindrance than -Et group.
