In 1, the carbonyl carbon is bonded to two hydrogen atoms. In 2, it is bonded to a hydrogen atom and a methyl group. Since the methyl group is larger than the hydrogen atom, steric hindrance is greater at the carbonyl carbon in Mens Margaritaville Up Leather Brown Shoes 8 Size Lace Boat 2Brown Lanvin Lace Size Men's Up Leather 9 8 Pebbled Oxfords US Dark Shoes nHZxnT8 than that in 1.
In 1, the nitrogen atom is bonded to three hydrogen atoms; in Up Mens 8 Boat Lace Size Leather Margaritaville Shoes Brown 2, it is bonded to three methyl groups. A methyl group is larger than a hydrogen atom. Thus, the steric hindrance at the nitrogen atom in 2SIDER Red Mens AUTHENTIC TOP Neon 13 SHOE Sahara 0271892 SPERRY BOAT Sz Leather Wx8gnv is greater than that in 1.
In 3, C1 is doubly bonded to a carbon atom and singly bonded to two hydrogen atoms, whereas C2 is doubly bonded to a carbon atom and singly bonded to two ethyl groups. An ethyl group is larger than a hydrogen atom. Thus, the steric hindrance at C2 is greater than that at C1.
