BALOCHISTAN MDCAT PAPER 2022 ( PART 12 ) 1. Bein-Haber cycle is used to calculate? Enthalpy of ionization Enthalpy of combustion Lattice energy of covalent compounds Lattice energy of ionic compounds 2. Why do electrons have opposite spins when they are in the same orbital? This condition reduces friction This condition results in zero magnetism and removes the charge of the electron This condition results in less repulsion and opposite magnetic fields This condition creates more energy 3. Viscosity of liquid decreases with an increase in: Temperature Atmospheric pressure Molecular mass Intermolecular forces 4. With the increase in the value of Principal Quantum number ‘n’ the size of the s-orbitals? May or may not remain the same Increase Decrease Remain the same 5. Which of the following is not a primary bond? Hydrogen bond Covalent bond Dative bond Ionic bond 6. Which of the following has sp3 hybridized carbon? 2-Butyne 1-Butene Benzene 1-Pentene 7. Which one of the following is not a crystalline solids? Copper sulphate Sugar NaCI Rubber 8. Bond energy is expressed in: Volt Joules Calories KJ/mol 9.
