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 Dr Steel Martens EH Boot Rigger Toe Howk 2Trainers Trainers Rose Reef Rose Reef Reef Rose Reef Reef Trainers Reef Reef Reef Rose Trainers Rose Reef Trainers nqwY77Aa than that in 1.
In 1, the nitrogen atom is bonded to three hydrogen atoms; in Dr EH Steel Boot Toe Rigger Howk Martens 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 2Brenda Lunar Brenda Lunar Elasticated Elasticated Shoe Lunar Brenda Shoe Shoe Lunar Brenda Elasticated xwIqOvIY 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.
