Options
- AN - N bond order less than 3 N - O bond order more than 1
- BN - N bond order greater than 3 N - O bond order less than 1
- CN - N bond order less than 1 N - O bond order greater than 1
- DNone
Correct answer
A. N - N bond order less than 3 N - O bond order more than 1
Step-by-step solution
Bond order is defined as the number of bonds present between two bonding atoms in a molecule or compound. In general, the bond order of N ≡ N is 3, and that of N - O is 1 . Bond length and bond order are inversely proportional to each other. If bond order increases, the bond length decreases, and if bond order decreases, the bond length increases. Bond length follows the order : Triple   Bond   <   Double   Bond   <   Single   Bond The N 2 O molecule exhibits the phe
