For each pair, the compound with thehigher boiling point is to be identified. Concept introduction: If the molecular weight is the same, then aldehydes and ketoneshavea higher boiling point than that of their corresponding hydrocarbons. The alcohol of the same molecular weights has a higher boiling point than that of their corresponding aldehydes and ketones due to the hydrogen bonding in alcohol.

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.
