The way by which the given synthesis is being accomplished has to be shown and explanation for the stereoselective synthesis of 10-trans-12-cis isomer. Concept introduction: Wittig Reaction: It is an organic reaction where an aldehyde or a ketone gets converted to an alkene by replacing carbonyl group by a C = C bond. A phosphorous ylide is used for this conversion. It is a neutral molecule where a positively charged phosphorous is attached to a negatively charged carbon atom. Non-stabilized ylide (having electron donating group on negatively charged carbon) gives Z-isomer whereas stabilized ylide (having electron withdrawing group on negatively charged carbon) gives E-isomer. Non–stabilized ylide (having electron donating group on negatively charged carbon) gives Z–isomer whereas stabilized ylide (having electron withdrawing group on negatively charged carbon) gives E–isomer.

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.
