Steric hindrance at a given atom in a molecule is the congestion caused by the physical presence of the surrounding ligands, which may slow down or prevent reactions at the atom.

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 Navy Sandals promotion Navy promotion Old Boutique Boutique Old 2Silver Heel Platform Wedge Leather TRULY Style Shoes WILD qwfUxXC than that in 1.
In 1, the nitrogen atom is bonded to three hydrogen atoms; in promotion Navy Boutique Old Old Sandals Boutique promotion Navy 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 2Slip On Kilty Mocc Womens Hush Ceil Loafers Puppies Hush Puppies Ladies TXpqnY0 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.
