Q. No 21..plz help me in this

Answer 1

Answer:

(c) CHCl3

Explanation:

as we know that C-H bonds are non polar , the dipole moment depends on the more electro negative atom i..e, Cl

therefore more the number of Cl atoms , more the polarity

but in option (D) the dipole moments ( directed from Cl to C ) will get cancelled to each other as CCl4 is tetrahedral

now comparing option (b) and (c) , we have more Cl in (c) than (b)

therefore option (c) is correct as per the above explanation
