The boiling point of pentane is higher than that of propane because?
carbon-carbon single bonds are stronger than carbon-hydrogen bonds.
Pentane has more covalent bonds to break
Pentane does not burn easily as
propane
The intermolecular forces in pentane are stronger than those of propane
Maelezo
The boiling points of alkanes increase with increasing number of carbons. This is because the intermolecular attractive forces, although individually weak, become cumulatively more significant as the number of atoms and electrons in the molecule increases.
