Space steric effect
The steric effect is also called the stereo effect. Mainly refers to the intramolecular tension caused by the steric hindrance caused by the proximity of certain atoms or groups in the molecule to each other and from the normal bond angle. The steric hindrance effect mainly refers to the steric hindrance caused by the proximity of certain atoms or groups in the molecule. Such as steric hindrance in the enzymatic reaction will reduce its catalytic activity. In a coordination compound, when a certain larger group is introduced into a ligand, it affects its formation of a coordination compound with a central atom due to steric hindrance. The fact that space has an effect, each atom occupies a certain space in the molecule. If the atoms are too close together, two adjacent atoms will form an overlapping electron cloud (expressed as a repulsive force), which may affect the reaction of the molecule and the preferred shape (structure).
