The reagent has to be given for the conversion of A to Tamoxifen. Concept introduction: The Grignard reaction: Alkyl, vinyl, or aryl-magnesium halides ( RMgX ) is called as Grignard reagent. Grignard reagent is reaction with carbonyl compound such as aldehyde or ketone , produces corresponding alcohol is the product and it is the one of the carbon – carbon bond forming reaction. Dehydration reaction: Removal of water molecule from the reaction when the alcohol is treated with strong acid like sulfuric acid. Alcohol is reaction with concentrated sulfuric acid, first alcohol gets protonated forms carbocation (more stable carbocation) followed by elimination of proton ( H + ) yields alkene as a product. The stability of carbocation is given below, Tertiary carbocation is more stable than the secondary, secondary carbocation is more stable than primary. In dehydration reaction, sulfuric acid is act as a proton donor, and which is used to protonate the alcohol and makes carbocation therefore sulfuric acid is the driving force of the reaction. Dehydration reaction will not go without acid (sulfuric acid).

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.
