BNO2 and O3

Step-by-step explanation

AIEEE 2003 Chemistry - Chemical Bonding & Molecular Structure Question 240 English Explanation 1
Here total = 1 + 2 0
AIEEE 2003 Chemistry - Chemical Bonding & Molecular Structure Question 240 English Explanation 2
total = 1 2 = 0
AIEEE 2003 Chemistry - Chemical Bonding & Molecular Structure Question 240 English Explanation 3
total = 1 + 2 0
AIEEE 2003 Chemistry - Chemical Bonding & Molecular Structure Question 240 English Explanation 4
1 + 2 + 3 = 4

   total = 0

In NO2 and O3 have permanent dipole moment as both of them are not symmetric molecule.

In CO2 and SiF4 each individual bond c = O and S- F have dipole moment but because of symmetric structure individual dipole moment get's cancelled.
