Answer 1

a)

CO2 is non polar molecule due to its linear shape

SO, only force will be

London dispersion forces

b)

This is polar molecule but it can’t form hydrogen bonding because for hydrogen bonding to be formed Hydrogen must be bonded to either of nitrogen, oxygen or fluorine

London dispersion forces

c)

Ne is just 1 atom

SO, only force will be

London dispersion forces

d)NH3 has hydrogen attached to nitrogen.

It is polar as well due to lone pair on Nitrogen
