The given starting molecule and treated with a selective reagents to give different type of products and target molecule transformation should be draw and identified in acid-catalyzed conditions. Concept introduction: Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition reaction. Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E1 (the reaction depends only on the substrate involved in the reaction) or E2 (the reaction depends on both of the substituents in the reaction) mechanism. Acid Catalyzed Hydration Reaction: The reaction involves breaking of π-bonds between carbon-carbon multiple bonds and addition of alcohol to more substituted position of carbon in the molecule. Grignard Reaction: This is a organometallic reaction in different alkyl, aryl-magnesium halides add to a carbonyl group in an aldehyde and ketone . This reaction is an important for the conversion of carbon-carbon single ( − C − C − ) bond. Moreover the addition of a reagent to an aster, lactone gives a tertiary alcohol in which will alkyl groups are the same and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone. To identify: The selective reacted used to accomplish the given transformation (a).
