The dipeptide, Gln-Gly, on treatment with CH₃COCl followed y aqueous work up gives :

The major product formed in the following reaction is :

Two 5 molal solutions are prepared by dissolving a non-electrolyte non-volatile solute separately in the solvents X and Y. The molecular weights of the solvents are M_x and M_y, respectively where M_x = $${3 \over 4}$$ My. The relative lowering of vapor pressure of the solution in X is ''m'' times that of the solution in Y. Given that the number of moles of solute is very small in comparison to that of the solvent, the value of ''m'' is :

At a certain temperature in a $$5$$ $$L$$ vessel, 2 moles of carbon monoxide and 3 moles of chlorine were allowed to reach equilibrium according to the reaction,
         CO + Cl₂ $$\rightleftharpoons$$ COCl₂
At equilibrium, if one mole of CO is present then equilibrium constant (K_c) for the reaction is :
