Re: Previous year Question Papers of Chemistry of 12th of CBSE Board

Yeah sure, here I am sharing the Chemistry Question Paper of CBSE 12th Board

1 Bond enthalpy of fluorine is lower than that of chlorine, why?
2 On increasing temperature, activation energy of a reaction decreases, why?
3 Write the reaction when glucose is heated with excess of HI.
4 Which Xe compound has distorted octahedral shape?
5 What is the denticity of co-ordination compound used for the treatment of lead Poisoning?
6 An alkoxide is a stronger base than hydroxide ion. Justify.
7 State the law which helps to determine the limiting molar conductivity of weak electrolyte.

Rest of the Questions are attached in below file which is free of cost
