Which one of the following should have the lowest boiling point? hcl ph3 h2s c2h6 c3h7oh

Explanation:

The boiling point depends on the intermolecular forces between the molecules of the compound.

have dipole- dipole interactions because there is the difference in electronegativity values of the atoms in the molecules.

posses hydrogen bonding.

: The bond in the molecule is C-H, which is non-polar in nature because the carbon and the hydrogen having very similar electronegativity values.

The intermolecular force acting in the molecule are induced the dipole-dipole forces or London Dispersion forces / van der Waals forces which are the weakest intermolecular force.

Hence, it has the weakest bond, so it takes least amount of the energy and hence the lowest boiling point.

have a great day because if you dont you and i will be sad
