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