The former reactant is called "1, 2- propylene oxide", which is abbreviated as propylene oxide; The latter reactant is called "monomethylamine" for short.

N above the amino group is rich in electrons, and C connected to O is poor in electrons. When nucleophilic reaction occurs between them, propylene oxide rings.

N forms a bond with C, and an H on the amino group is rearranged into O to form hydroxyl.

The product name is "N- methyl isopropanolamine", and the structural schematic diagram is as follows:

This reaction belongs to nucleophilic ring-opening reaction.

Attached:

Propylene oxide is a chiral molecule (No.2 carbon is a chiral atom), and there are two mirror isomers.

N- methyl isopropanolamine is also a chiral molecule, and the No.2 carbon atom and nitrogen atom are both chiral atoms, so there are four mirror isomers.
