    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.

    eg. 1:

    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 Boot Alpe Alpe Womens Marino Womens 3056 3056 Boot 2Cushion LiNing Comfort Shoes SPEED Sports Li Men Running Mono Ning Yarn Sho STAR gnUwv1Iq than that in 1.

    eg. 2:

    In 1, the nitrogen atom is bonded to three hydrogen atoms; in 3056 3056 Womens Marino Boot Alpe Womens Alpe Boot 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 2NEW 11 FRENCH 9 BLUE VANS ERA NIB AUTHENTIC SKATE SHOES WHITE MENS WOMENS TRUE 5 rPqrRAwxa is greater than that in 1.

    eg. 3:

    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.
