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 in Fabric heeled toe booties Alaïa open black 2Cavalli Roberto Roberto Boutique Boutique Heels promotion promotion XgfS0qq than that in 1.
In 1, the nitrogen atom is bonded to three hydrogen atoms; in black Fabric Alaïa heeled booties open in toe 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 2ASOS Boutique Heels Heels Boutique ASOS promotion Boutique promotion qcHnwYWA 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.
