The strongest type of intermolecular force present between NH2CH3 molecules is the Hydrogen bond
This is further explained below.
Generally, One definition of a hydrogen bond describes it as an electrostatic force of attraction between two electronegative atoms, one of which is a hydrogen atom that is covalently bound to a more electronegative "donor" atom or group and the other of which is an atom that bears a lone pair of electrons and is referred to as the hydrogen bond acceptor.
In conclusion, The hydrogen bond is the sort of intermolecular interaction that is the most powerful when it is present between NH2CH3 molecules.
