Question

In which of the following substances the molecules will have dipole-dipole interactions as their strongest intermolecular interaction? (Hint check the shape and polarity of the molecules)

Group of answer choices

CS₂(l)

NH₃(l)

Br₂(l)

CH₃Cl(l)

Answer 1

ANSWER The molecules in the met question are Carbon disulphide (652) (1) Ammonia (NHg) (1) Broomine (B2) (1) Methyl Chionide (Chizel) (2) (chorromethane) Among the 4, molecules, a Ntg have H-bonding as intermoleculan attraction. And we Know H-bonding is stronger than any dipole-dipole interaction. So, here dipole-dipole interaction alien not be their strongest intermolecvian interaction. intenaction. For Bre, it has no intermoleculan Left molecule is es, it has London dispension induced force as dipole a interaction, it is the one & only interaction of intermolecules ; & it is weaker than dipole - dipole interaction. u NHS bond of 2 IN NH

Now, the remaining molecule is Chacl. it has strongest dipole-dipole interaction 80, among u molecules Cizel has dipole dipole interaction as its strongest intermoleculan interaction.
