The number of carbon atoms present in a molecule of a pentose sugar is to be stated. Concept introduction: Carbohydrates are a class of organic compounds. They can be present in the form of open chains or rings. Carbohydrates usually contain an aldehyde or ketone with additional hydroxyl groups. They have the general molecular formula, CH 2 O .

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.
