Which of the two compounds shown has a higher boiling point is to be determined. Concept introduction: The boiling point of a compound depends on the strength of the intermolecular forces that exist between its molecules. The main types of intermolecular interactions in increasing order of strength are induced dipole-induced dipole, dipole-dipole, and hydrogen bonding. Polar molecules have both induced dipole-induced dipole interactions, and possibly hydrogen bonding too. Nonpolar molecules have only induced dipole-induced dipole interactions. Generally, nonpolar molecules have weaker intermolecular interactions than polar molecules of comparable size.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
