The validation of the fact that maltose gives a positive Benedict’s test has to be predicted. Concept introduction: Monosaccharides and most of the disaccharides give positive test with Benedict’s solution. It is used to detect the presence of aldehyde or alpha hydroxy ketones. A positive test with Benedict’s solution is confirmed by the formation of a brick-red precipitate.

Question

Q8: Propose an efficient synthesis of cyclopentene from cyclopentane.

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.
