Question

draw the lewis structure of the following molecule. use it to give the information

co₃

number of single bonds

number of double bonds

number of sigma bonds

number of pi bonds

number of unshared electrons

Explanation:

Step1: Calculate total valence electrons

Carbon has 4 valence electrons, each oxygen has 6. Total = 4 + 6×2 = 16.

Step2: Draw Lewis structure

Carbon is central. Double - bond each oxygen (O = C = O).

Step3: Count bonds

Single bonds: 0 (no single bonds in O = C = O).
Double bonds: 2 (two C = O double bonds).
Sigma bonds: 2 (each double bond has 1 sigma bond).
Pi bonds: 2 (each double bond has 1 pi bond).
Unshared electrons: Each O has 2 lone pairs. Total unshared electrons = 4×2 = 8.

Answer:

Number of single bonds: 0
Number of double bonds: 2
Number of sigma bonds: 2
Number of pi bonds: 2
Number of unshared electrons: 8
