Question

Consider the molecules/species SC N − ; H N 3 ​ ; C O 2 ​ ; C H 3 ​ CO O − ; C 2 ​ ( CN ) 4 ​ ; P h e n o l and CO Number of species that have atleast one bond whose bond order is NOT a whole number is_______

TestHub · Accepted Answer

Only C O 2 ​ and CO has no resonance, rest all molecules involve resonance thereby having atleast one bond having fractional bond order
