Question

Based on their composition and structure, list CH3Cl, CH2=CH2, and CH3CH2CH2OH in order of decreasing intermolecular forces. Rank the compounds from strongest to weakest intermolecular forces. To rank items as equivalent, overlap them.

Answer 1

Answer:

CH3CH2CH2OH > CH3Cl > CH2=CH2

Explanation:

Inter molecular forces are bonds or forces between two or more covalent molecules. These molecules can either be polar or non polar depending on the electronegativity differences between the atoms that make up the molecule.

There are 3 types of inter molecular forces namely:

• Van der waal forces (which is the weakest of them all)
• permanent dipole
• Hydrogen bonding (which is the strongest)

CH3CH2CH2OH has the strongest inter molecular force. It contains hydrogen bonding because of the presence of OH group in its molecule.

CH3Cl has permanent dipole between its molecules because of the presence of a strong electronegative element, Chlorine (Cl)

CH2=CH2 has the weakest inter molecular force because it has van der waal forces.
