reactivity of benzene

Toluene o-Nitrotoluene p-Nitrotoluene These groups (except halogens) increase the electron density at the ring through resonance effect. Thus the reactivity of benzene ring towards electrophilic substitution reactions increases. The substituents or groups which direct the incomi..

Nature of C-X Bond - The general formula of Haloalkane (CnH 2 n + 1 - X) or Haloarene is 'RX' where R - is an alkyl or aryl group and X is a halogen atom (F, Cl, Br or I). The halogen derived hydrocarbons are a highly reactive class of compounds. The reactivity is due to the pre..

>In the addition of HCN, NaHSO 3 , RMgX etc to carbonyl compounds the groups on the carbonyl compound that increases the positive charge on the carbonyl atom (i.e., electronegative group) will increase its reactivity towards the addition and vice versa. The order of reactivity i..

Compounds - A compound is a pure substance that is formed by the combination of atoms of two or more elements. The atom in a compound is chemically combined in a fixed and constant proportion. When compounds are formed, atoms of two or more elements combine chemically, by either transfer or by shar..

Electrophilic Substitution Reactions - All amino groups -NH 2 , -NHR, -NR 2 are most powerful activating groups in aromatic electrophilic substitution reactions are ortho and para directing. Aniline gets instantaneously brominated at all of the three O, p - positions to give a white precipitate. Th..
