Question

Assertion: Polar compounds contains polar bond , it is not necessarily.
Reason: If polar bonds in a molecule are symmetrically arranged, then their polarities will cancel and they will be non polar.

• A. true, true, correct explanation
  
• B. true, true, not correct explanation
  
• C. true, false
  
• D. false, true
  
• E. false, false
  

Answer 1

Answer: (A)

true, true, correct explanation

Assertion: Polar compounds contain polar bonds, it is not necessarily polar.

Because :

Reason: If polar bonds in a molecule are symmetrically arranged, then their polarities will cancel and the molecule will be nonpolar.

Thus both statements are correct and the reason is the correct explanation of assertion.

An example is linear $C{O}_2$ molecule with structure $O=C=O$. It contains polar carbon-oxygen bonds but the molecule, on the whole, is non-polar.

Hence the correct option is A.
