The common features, among the species CN, CO and NO are:
Correct answer: B. Bond order three and weak field ligands
- A. Bond order three and Isoelectronic
- B. Bond order three and weak field ligands
- C. Bond order two and π acceptors
- D. Isoelectronic and weak field ligands
Explanation
This question can be solved by ruling out the wrong options. First of all, CN, CO and NO do not have the same number of electrons so that can be termed as isoelectronic. This rules out options A and D. Option C is also wrong because the bond order of these elements is not two, it is three, and neither they are π acceptors, rather are ligands that possess the ability to donate an electron pair. Hence Option B is the correct option.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
