JEE Main 2003 — Chemical Bonding And Molecular Structure Question with Solution
From: AIEEE 2003
Question
Which one of the following pairs of molecules will have permanent dipole moments for both members
Choose an option
Show full solutionCorrect option: B
Correct answer
BNO2 and O3
Step-by-step explanation
Here total = 1 + 2 0
total = 1 2 = 0
total = 1 + 2 0
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.
