B) The formal charge on each O atom is -0.67 unit
C) It has two C-o single bonds one C-O double bond
D) The central carbon atom is sp3 hybridised
please help......​

Answer 1

Answer:

CO32- has three resonating structures. The way to calculate the bond order for most conpounds having resonating structures is:(No. of bonds/No. of resonating structures) Since, CO32- has 4 bonds, Thus answer will be 4/3 or 1.3333..
