nucleophilic substitution of haloalkane

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

In this type of substitution, atom or group of atoms in the molecule is replaced by a nucleophile. These can be either S N 1 (substitution, nucleophilic, unimolecular) or S N 2 (substitution, nucleophilic, bimolecular) type. In the S N 1 ..

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 rate-determining step. As ..

Haloalkanes on heating with alcoholic potash loses one molecule of hydrogen halide to give alkene. ..

. 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 in substitu..

Haloalkanes react with alcoholic solution of potassium cyanide (KCN) to give alkane nitriles or alkyl cyanides as the major products along with a small amount of alkyl isocyanides. Alkyl cyanides can further be converted into acid amides, carboxylic acids and primary amines under dif..

The halogen atom of haloalkane gets substituted by nitrite group (-O-N=O) when it is treated with sodium or potassium nitrite and forms alkyl nitrites. ..

The formation of thioalcohols or thiols takes place when haloalkane is treated with-sodium or potassium hydrogen sulphide: the halogen atom gets replaced by hydrosulphide (-SH) group. ..

When Haloalkanes are heated with an ethanolic solution of silver salt of a fatty acid these form esters. ..

R 2 C=CR 2 > R 2 C=CHR > R 2 C=CH 2 > RCH=CH 2 According to Saytzeff's rule, any alkyl halide which gives a more stable (i.e. more highly substituted) alkene must undergo dehydrohalogenation reaction faster than the one which gives a less stable (i.e. less highly substitut..
