a) Interpretation: The flaw in the reaction scheme given is to be identified and the corrected scheme is to be provided. Concept introduction: α,β-Unsaturated ketones when treated with Grignard reagents yield a product with the 1,2-addition of RH to the C = O bond in the ketone to yield a tertiary alcohol. The C = O group in ketones is reduced to a secondary alcohol by LiAlH 4 . To identify: The flaw in the reaction scheme given and to provide the corrected scheme.

Question

The kinetics of a gas phase reaction of the form A → Products results in a rate constant of 0.00781 M/min. For this reaction, the initial concentration of A is 0.501 M. How many minutes will it take for the concentration of A to reach 0.144 M

Answer 1

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.
