Question

What is the intermolecular forces of:

PF₅

CO₂

HCN

Ar

HOCl

CH₃OH

CH₄

NH₃

I₂

CH₃Cl

HCl

CH₃CH₂CH₂CH₃

Answer 1

Ans :-

Hydrogen bonding :- Present between those molecules which contains at least one H-F or H-N or H-O bond.

Dipole-dipole forces :- Present between those molecules which do not contains H-F or H-N or H-O bond.

Dispersion or London forces :- Present between noble gases or non-polar molecules.

Therefore,

What is the intermolecular forces of:

1). PF₅ (Polar which do not contain H-F/H-O/H-N bonds) = Dipole-dipole forces

2). CO₂(Non-polar) = Dispersion or London forces

3). HCN (Polar which do not contain H-F/H-O/H-N bonds) = Dipole-dipole forces

4). Ar (Noble gas or non-polar) = Dispersion or London forces

5). HOCl (Polar which contain H-O bond) = Hydrogen bonding

6). CH₃OH (Polar which contain H-O bond) = Hydrogen bonding

7). CH₄(Non-polar) =  Dispersion or London forces

8). NH₃(Polar which contain H-N bond)= Hydrogen bonding

9). I₂ (Non-polar) = Dispersion or London forces

10). CH₃Cl (Polar which do not contain H-F/H-O/H-N bonds) = Dipole-dipole forces

11). HCl (Polar which do not contain H-F/H-O/H-N bonds) = Dipole-dipole forces

12). CH₃CH₂CH₂CH₃ (Non-polar) = Dispersion or London forces
