Consider the following statements regarding homonuclear diatomic molecules according to Molecular Orbital Theory: (I) In the C ₂ molecule, the double bond consists of two bonds. (II) The B ₂ molecule is paramagnetic in nature. (III) The highest occupied molecular orbital in the ground state of N ₂ is a 2p orbital. (IV) The O ₂ molecule contains two unpaired electrons in its ^ * antibonding orbitals. How many of the a

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

C. 3

Step-by-step solution

Let us evaluate each statement based on Molecular Orbital Theory: (I) Correct: C ₂ (12 electrons) has the configuration 1s^2 (II) Correct: B ₂ (10 electrons) has the configuration 1s^2 (III) Incorrect: N ₂ (14 electrons) has the configuration 1s^2 (IV) Correct: O ₂ (16 electrons) has the configuration 1s^2 Therefore, exactly 3 statements are correct. Answer: 3
