Answer 1

a) Ethylamine

It is a primary amine.

In these, the forces that exist are London's forces, dipole dipole forces and hydrogen bonds.

Strongest : hydrogen bonds.

b) flourotrichloromethane

It is a halogen containing compound.

Existing forces are London's forces and dipole dipole forces

Strongest : dipole dipole forces

c) Pentane

Existing forces are London's forces.

These are the only forces.

d) Ethanol

Existing forces : London's forces, Dipole dipole forces and Hydrogen bonds

Strongest : Hydrogen bonds

e) Chloroform

Existing forces : London's forces, Dipole dipole forces

Strongest : Dipole dipole forces
