Correct order of decreasing reactivity of nucleophillic addition in case of HCHO, CH3CHO and CH3COCH3 is (a) CH3 COH3 > CH3CHO > HCHO (b) HCHO > CH3CHO > CH3COCH3 (c) CH3COCH3 > HCHO > CH3CHO (d) CH3CHO > HCHO > CH3COCH3 |
| Answer» TION:Reactivity increases in the order: #C_6H_5C(=O)CH_3; H_3C-C(=O)CH_3; H_3C-C(=O)H#Explanation:Consider the organic SHRUBBERY substituting the carbonyl group. Phenylacetone has a WHOPPING great PHENYL group; acetone has 2 methyl groups, versus acetaldehyde, 1 methyl, and 1 hydrogen.Now it is well-known that aldehydes are much more reactive than ketones, so acetaldehyde is the MOST reactive. Next comes the ketone, acetone, and least reactive to SUBSTITUTION is the phenylacetone. | |
