The principal product in each of the given reactions is to be predicted. Concept introduction: The conjugate base of alkyne acts as a good nucleophile. On reaction with primary alkyl halide , it undergoes substitution reaction. The order of better leaving group of halogen in a nucleophilic substitution reaction is I > Br > Cl > F . Alkynes , on hydrogenation with catalyst Lindlar palladium, undergo syn addition and yield cis alkene . Alkynes, on hydration, undergo addition of a molecule of water. The hydrogen atom is bonded to less substituted triple bonded carbon, and the hydroxyl groupis bonded to more substituted triple bonded carbon atom and forms a ketone through enol formation. Germinal and vicinal dihalides, on reaction with a strong base, undergo double dehydrohalogenation and form alkynes. Ozonolysis of alkynes involves the cleavage of triple bond and formation of carboxylic acids as products. An acyclic alkyne forms two carboxylic acids whereas a cyclic alkyne forms a single product with two carboxylic acid groups.

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.
