mechanism of nucleophilic substitution reactions

In the C-X bond there is a partial positive charge on the carbon atom and negative on the halogen atom. Thus nucleophilies attack the electron deficient carbon resulting in the displacement of the weaker nucleophile, the halide ion. Reactions of alkyl halides are generally ..

The nucleophilic substitution reactions can be classified into two types: First is the S N 1 reaction (substitution nucleophilic, first order). This type of reaction proceeds in two steps as: The first step is slow and is ..

The chemical reactions of haloalkanes can be divided into four types: Nucleophilic substitution reactions Dehydrohalogenation Reactions with metals Reductio..

. Depending upon the type of attacking reagent, the addition or substitution reactions are also classified as free radical, electrophilic or nucleophilic substitution or addition reactions. For example, if the attacking reagent is nucleophile..

Alkynes also give the following nucleophilic addition reactions..

Being unsaturated, aldehydes and ketones undergo addition reactions. They have a polar carbonyl group. The carbon of the carbonyl group being electrophilic, is readily attacked by the nucleophiles. Hence the most typical reactions of aldehydes and ketones are nuc..

Aldehydes and Ketones are highly reactive compounds. They undergo similar reactions because of the presence of a carbonyl functional group in both of the..

The reactions in which an atom or group of atoms in a molecule is replaced or substituted by different atoms or group of atoms are called substitution reaction. For example, These reactions can be of two types: ..

Due to their acidic nature, alkynes form metallic salts called alkynides e.g., sodium, silver and copper(ous) salts. Examples are, ..

High concentration of nucleophile favors S N 2 , while low concentration favors SN 1 mechanism..
