Question

Which of the following molecules experience dipole-dipole forces as its strongest IMF? A) H2 B) SO2 C) NH3 D) CF4 E) BCl3

Answer 1

Answer:
`NH_3`

Explanation:

a)
`H_2`: This is a non polar covalent compound which are held by weak vanderwaal forces of attraction.

b)
`SO_2`: This is a covalent compound which is polar due to the presence of lone pair of electrons and are held by dipole-dipole forces of attraction.

c)
`NH_3`: These are joined by a special type of dipole dipole attraction called as hydrogen bond. It forms between electronegative nitrogen atom and hydrogen atom and is the strongest interaction.

d)
`CF_4`: This is a covalent compound and is non polar which are held by weak vanderwaal forces of attraction.

e)
`BCl_3`: This is a covalent compound and is non polar which are held by weak vander waal forces of attraction.
