Why are the protons attached to N in the first 2 amides selectively deprotonated by a base while in the third amide, the methyl attached to the carbonyl group is deprotonated? || .C NH2 CH3 NHCH3 CH CH3 NCH3 CH3 A) The methyl group is sterically hindered and, thus, the approach of a base is partially blocked B) The 2 methyl groups attached to N in the 3rd amide blocked the approach of the base during deprotonation C) The hydrogen attached to the N in the first 2 amides is more acidic than the methyl hydrogens next to the carbonyl group D) The hydrogen attached to the N in the first 2 amides is less acidic than the methyl hydrogens next to the carbonylgroup E) None of the above
