Solution


Q.

Choose the polar molecule from the following.               [2024]
1 CCl4  
2 CO2  
3 CH2=CH2  
4 CHCl3  

Ans.

(4)

In CCl4, CO2 and CH2=CH2, individual bond moments cancel out to give a net zero dipole moment. In CHCl3, because it is not a symmetrical molecule, vector sum of bond moments is not zero i.e. it is a polar molecule.
