Sterically Hindered Definition:
Steric Hindrance is a phenomenon that prevents chemical reactions because of the large sized groups on the molecules. This bulky region of the molecule is therefore said to be sterically hindered.
Sterically Hindered Explained:
Molecules are not sterically hindered as a whole, instead, there are sterically hindered positions within a molecule. There are certain qualities that determine whether it is hindered or not.
- The smaller the size of atom attached to the carbon the less will be the steric hindrance.
- Bulkier the group more will be the steric hindrance.
- Hydrogen is the smallest atom with least steric hindrance.
