The compound A is to be identified and mechanism for its synthesis is to be stated. Concept Introduction: Grignard reagent reacts with the nitrile to form ketones . This reaction is similar to the reaction of Grignard reagent with aldehydes or ketones. The strong nucleophile of Grignard reagent reacts with strong carbon nitrogen triple bond of nitrile group. The reaction proceeds via imine intermediate formation which upon hydrolysis forms ketone.

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.

Part II. two unbranched ketone have molecular formulla (C8H100). El-ms showed that both of them have a molecular ion peak at m/2 =128. However ketone (A) has a fragment peak at m/2 = 99 and 72 while ketone (B) snowed a fragment peak at m/2 = 113 and 58. 9) Propose the most plausible structures for both ketones b) Explain how you arrived at your conclusion by drawing the Structures of the distinguishing fragments for each ketone, including their fragmentation mechanisms.
