Understanding Chemistry. NUCLEOPHILIC ADDITION / ELIMINATION MECHANISMS MENU. What is nucleophilic addition / elimination? . . . Includes an explanation of all the terms involved, together with a general mechanism for these reactions. It would be useful to read this before you look at specific examples.
An explanation of the terms nucleophile and nucleophilic addition / elimination, together with the general mechanisms for these reactions involving acyl chlorides (acid chlorides).
Chemguide – answers. NUCLEOPHILIC ADDITION: C="O" and HCN. 1. a) Because oxygen is more electronegative than carbon, the carbon-oxygen double bond is strongly polarised, with the oxygen being fairly negative and the carbon fairly positive. The lone pair on the negatively charged carbon in the cyanide ion is
ADDITION-ELIMINATION REACTIONS OF ALDEHYDES AND KETONES. This page looks at It also looks briefly at some other similar reactions which are all known as addition-elimination (or condensation) reactions. The reaction with 2 In terms of mechanisms, this is a nucleophilic addition-elimination reaction. The 2
Facts and mechanisms for the reactions between carbonyl compounds (aldehydes and ketones) and hydrogen cyanide, HCN - nucleophilic addition.
Facts and mechanism for the reaction between an acyl chloride (acid chloride) and an amine to produce an N-substituted amide - nucleophilic addition / elimination.
Understanding Chemistry. NUCLEOPHILIC ADDITION MECHANISMS MENU. The addition of hydrogen cyanide to aldehydes and ketones . . . Facts and mechanism for the nucleophilic addition of hydrogen cyanide, HCN, to aldehydes and ketones. The reduction of aldehydes and ketones . . . Facts and a simplified
Chemguide – answers. NUCLEOPHILIC ADDITION: REDUCING C="O". 1. a) The carbon-oxygen double bond is strongly polarised because oxygen is more electronegative than carbon; the carbon atom becomes fairly positively charged. The lone pair on a hydride ion is attracted towards this carbon, and moves to form a
ADDITION / ELIMINATION REACTIONS. 1. Ethanoyl chloride, CH3COCl, a typical acyl chloride, reacts instantly with water to produce ethanoic acid and fumes of hydrogen chloride. The mechanism for the reaction is as follows: Stage 1: Stage 2: Stage 3: a) In stage 1, the water is acting as a nucleophile. What is a
