substitution and elimination reactions

The reactions in which a small molecule is removed from adjacent carbon atoms resulting in the formation of additional (multiple) bond between them are called elimination reactions. For example,..

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 m..

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..

The halogen atom is ortho and para directing and therefore, substitution takes place at ortho and para positions giving electrophilic substitution reactions at the benzene ring. In the resonance structures of chlorobenzene the ortho and para positions get negatively c..

Haloalkanes undergo elimination of hydrogen halide (HX) when boiled with alcoholic solution of potassium hydroxide, resulting in the formation of alkenes. As the hydrogen atom present at b -position of haloalkane (i.e., on the carbon atom next to the one carrying the halogen) is removed..

A substitution or displacement reaction is a chemical change in which atoms of one element replace the atoms of another element from the molecules of a compoun..

Electrophilic Substitution Reaction - Aromatic aldehydes and ketones undergo electrophilic substitution at the ring in which the carbonyl group acts as a deactivating and meta-directing grou..

Displacement or Substitution Reaction - A substitution or displacement reaction is a chemical change in which atoms of one element replace the atoms of another element from the molecules of a compound. Elements which are higher in the Activity Series displace..
