Predict the shapes of the following molecules on the basis of hybridisation. BCl_(3),CH_(4),CO_(2),NH_(3)

Addition of non-volatile solute to a solvent always increases the colligative properties such as osmotic pressure. Delta P . Delta T_b and Delta T_f . All these colligative properties are directly proportional to molality if solutions are dilute. The increases in colligative properties on addition of non-volatile solute is due to increases in number of solute particles. For different aqueous solutions of 0.1 N NaCI, 0.1 N urea, 0.1 N Na_2SO_4 and 0.1 N Na_3PO_4 solution at 27^@C , the correct statements are : 1. The order of osmotic pressure is NaCI = Na_2SO_4 = Na_3PO_4 = urea 2. pi = (Delta T_b)/k_b xx RT for urea solution 3. Addition of salt on ice increases its melting point 4. Addition of salt on ice bring in melting of ice earlier
