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.

Explanation of Solution

Sugar molecules can be named as D or L sugars according to their most oxidized carbon at the top of the Fisher projection. The absolute configuration of a molecule can be explained using D and L configuration. In D- sugars, the OH group on the bottom chiral center points to the right while in L- sugars, the OH group on the bottom chiral center points to the left. Aldopentose is a five-carbon aldehyde sugar. Xylose, Arabinose and Ribose are few examples.
