what is substitution

In this type of substitution, an electrophile attacks the carbanion of the substrate substituting one of the hydrogens or other group..

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, In substitution reactions the hydrogen of the alkane molecule is replaced by another..

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: ..

At elevated temperatures (500°C), higher alkenes give substitution products with chlorine. For example, CH 3 -CH=CH 2 + Cl 2 ClCH 2 -CH=CH 2 +HCl propene 3-chloropropene Branched-chain alkenes give substitution..

Electrophilic Substitution - The nitro group strongly deactivates the benzene ring towards electrophilic substitution. Nitro group is electron withdrawing group and thus causes electron deficiency at ortho and para positrons as is clear from the resonating structures of nitro be..

Differentiation by Substitution - Differentiation of certain functions seem to be very difficult, but by suitably substituting the independent variable with some trigonometric function or other functions, they can be differentiated easily.Differentiation of certain functions see..

The nitro group strongly deactivates the benzene ring towards electrophilic substitution. Nitro group is electron withdrawing group and thus causes electron deficiency at ortho and para positrons as is clear from the resonating structures of nitro benzene. ..

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 reaction only one molecule is ..

Solve 2x - 9y = 0 (i) x - 18y = 27 (ii) From (i) 2x - 9y = 0 2x = 9y (iii) Substituting this value of x in (ii), we get, 9y - 36y = 54 - 27y = 54 y = -2 Substitute this value of y in (iii): = - ..

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