Two possibilities of Compound X; a chemical test has to be distinguished between two possibilities. The structure of Compound X has to be determined. Concept introduction: Wohl degradation: The reverse process of Kiliani-Fischer synthesis and involves the removal of a Carbon atom from an aldose. The aldehyde is first converted to a cyanohydrin, followed by loss of HCN in the presence of a base. This chain reduction only gives only one product, in contrast with the chain lengthening (Kiliani-synthesis) gives two products.

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.

These two reactions appear to start with the same starting materials but result in different products. How do the chemicals know which product to form? Are both products formed, or is there some information missing that will direct them a particular way?

You can draw them in any arrangement you like. • Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is. • Note: if one of your reagents needs to contain a halogen, use bromine.
