(a) Interpretation: The two different methods to carry out the given transformation; a one-step method using a Wittig reaction, and a two-step method using a Grignard reagent are to be stated and the preferred route is to be identified. Concept introduction: The Wittig reaction is always preferred for the synthesis of alkene rather than other elimination reactions. The mostly elimination methods generally gives mixture of constitutional isomers, through E1 reaction.

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.
