(C 2 H 3 N) whioh is a cyanide. The compound 'B' on partial hydrolysis gives 'C' (C 2 H 5 ON) which is a neutral compound. 'C' on treatment with Br 2 and NaOH gives. 'D' (CH S N), which turns red litmus blue. 'D' on reaction with nitrous acid gives back 'A'. L Identify the compounds A, B, C and D i..

The heat required to raise the temperature of any substance by 1 C, is called the heat capacity (C) of that substance. If the temperature of the substance is increased by 1 C at constant volume heat capacity is mentioned as Cv and if the temperature of the substance is raised by 1 C at constan..

. For example : Chlorine and oxygen are non-metals because they form negative ions by gain of 1 and 2 electrons respectively. CI + e" cr O +2e" -> Q 1 ~ _ The number of electrons lost or gained by an element is equal to its valency. Metals constitute the mineral wealth of a country. Th..

This crystalline form of carbon is made of porous cage like arrangement of carbon atoms. Fullerene having C2 n structure have spherical arrangement of atoms. Its two important members have Cg 0 and C 70 atoms. Crystalline fullerene was first prepared by evaporation of graphite using lasers..

The degree of polarity of a polar molecule is measured in terms of dipole moment. Dipole moment is defined as the product of magnitude of a charge and the distance between two opposite charges Dipole moment, (a = (charge on the polar ends) x distance between the ends H = q..
