It is to be shown how the given synthesis would carry out using necessary reagents. Concept introduction: Sodium hydride (NaH) is an ionic hydride and thus a strong base; it can be used to abstract the proton, resulting in the formation of nucleophile. Lithium dialkylcuprates ( R 2 CuLi ) are weak R - nucleophiles that favor conjugate addition over direct addition. The Wittig reaction is one of the primer methods of preparation of alkene from aldehyde or ketone using a reagent called ylide. The ylide is a neutral molecule having positively charged phosphorous atom bonded to negatively charged carbon atom. The negatively charged carbon of an ylide acts as a nucleophile and attacks the electrophilic carbon of carbonyl group and forms betaine, which has the negative charge on oxygen and positive charge on phosphorus atom.

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.
