The expected structure of the product from the reaction of isopropyl benzene with each of the given reagents is to be written. Concept introduction: Hydrogenation of benzene requires three molar equivalents of hydrogen. The product formed is cyclohexane. Reaction of sodium and ethanol in liquid ammonia reduces arenes to dienes which are non-conjugated. Alkyl substituents, if any, are present on the double bond in the conjugated diene formed. Sodium dichromate, in the presence of sulfuric acid, forms chromic acid which is an oxidizing agent. It oxidizes alkyl side chain of benzenes, which have at least one benzylic hydrogen, to carboxylic acid group. Using N-bromosuccinimide , the benzylic hydrogen is selectively substituted by bromine. Tertiary alkyl halides preferably undergo elimination when a strong base like ethoxide is used. The halogen atom and hydrogen atom are eliminated, and a double bond is formed.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
