Question

bond order of HCO2^-​

Answer 1

Answer:

The bond order of H2O is 2, and that of NH3 is 3, which makes sense, when considering the number of bonds they have.

However, if using basic group theory, you get the MO diagrams as presented in this paper:

Answer 2

Complete question:

Calculate the C-O bond order in ${HCO}^{ - }_{ 2}$ molecule is: (1) 1.33 (2) 1.5 (3) 1.47 (4) 0.80

Answer:

The C-O bond order is (1) 1.33.

Explanation for the answer:

• The number of chemical bonds present between two atoms of a molecule is called a bond order.
• It measures bond stability.
• It is inversely proportional to the bond length.
• Total Bonds = 4
• Between atoms = 3
• Thus, Bond order = 4/3 = 1.33
• Hence, the correct answer among all the options is option (1) 1.33.
