Question

Draw a simple molecular orbital diagram for the following molecules. O₂².... N₂^+.... C₂2- '''a. Is the ion paramagnetic or diamagnetic? b. What is the bond order in the ion? c. Would these ions have longer, shorter, or the same bond length as their neutral counterpart? d. Would these ions have stronger, weaker, or equal bonding strength as their neutral counterparts

Answer 1

Bond order

The number of bond present between a molecule which gives strength to that molecule is known as bond order

Bond length

The distance between the nucleus of two molecule is known as bond length.

Relationship between bond length and bond order

Now for the given molecules , the molevcular orbitals and thier bond order and bond lengths are given in the following figures

Now for the molecule O₂^2- and O2(neutral counterpart), the small bond length will be obtained by O₂ and have high strength than O₂^2-

Now for the molecule N₂⁺ and N2(neutral counterpart), the small bond length will be obtained by N₂ and have high strength than N₂⁺

Now for the molecule C₂^2- and C2(neutral counterpart), the small bond length will be obtained by C₂^2- and have high strength than C₂
