Depict the hydrogen bonding between two ammonia molecules and between one ammonia molecule and one water molecule?

Hydrogen bondings are shown below.

Explanation:

Hydrogen bonding takes place between an electronegative atom (O, N and F) and H atom attached to those electronegative atoms (O, N and F). Lone pairs on electronegative atoms are involved in formation of hydrogen bond.

Electronegative atom of a molecule which donates it's lone pair to form hydrogen bonding is called hydrogen bond donor. And the other molecule whose H atom is involved in hydrogen bonding is called hydrogen bond acceptor.

Hydrogen bond is a kind of bond whose strength is an intermediate to ionic and covalent bond.

Hydrogen bonding is represented as dash lines.

Hydrogen bonding between ammonia molecules and between ammonia and water molecule has been shown below.

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
