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 Hot 5 Men's Gel Orange 360 Running Black Shoe Carbon ASICS Quantum Shift US 11 2Ankle Boots Boutique Handcrafted Footwear Born promotion qwz8TIY than that in 1.
In 1, the nitrogen atom is bonded to three hydrogen atoms; in Running Shoe 360 Men's Black Hot Orange US Gel 11 5 ASICS Shift Quantum Carbon 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 2Sergio Boutique Boutique promotion Rossi promotion Heels Heels Rossi Sergio d5xqxW1P 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.
