Bond Order of Kr2, B2, C2, N2 respectively areA+0,+3,+1,+2B+2,+3,+1,0C+3,+2,+1,0D+1, +3, +1,0E+2, +2, +1,0FQ,+1,+2,+3 The Correct Answer and Explanation is : To calculate the bond order of diatomic molecules like ( \text{Kr}_2, \text{B}_2, \text{C}_2, \text{N}_2 ), we need to consider the molecular orbital theory. The bond order is given by the formula: [\text{Bond Order} = \frac{1}{2}

The Angular Frequency Of A Simple Pendulum Depends On Its Length And On The Local Acceleration Due To Gravity. The Correct Answer and Explanation is : The rate at which the angular displacement (θ) of a simple pendulum changes with respect to time (dθ/dt) is known as its angular velocity. This quantity is directly related
