Group of molecules having zero dipole moment
is
a. CO2, BF3, H2, NH3, SO3, CCl4 and CS2
b. CO2, BF3, HCI, N2, SO3, CCl4 and CS2
C. CO2, BF3, H2, N2, SO3, CCl4 and CS2
d. CO2, BF3, H2, N2, SO2, CCl4 and CS2
Please explain the answer.

Answer:
c option is correct
Explanation:
a and b options are easily eliminated due to presence of NH3 and HCl because it is known that dipole moment for these molecules is not zero.
between c and d there is only difference of SO2 and SO3, so let's clear the difference between them
SO2: dipole moment is not zero because of the bent shape of the molecule caused due to presence of lone pair on sulphur atom.
SO3: dipole moment is zero because triangular planar structure the individual dipole moments cancel out each other so net dipole moment will be zero.
hope it helps.....
Answer:
(c) is the correct answer
Explanation:
CO2 is linear. dipole moment=0
BF3 is trigonal planar ; resultant dipole moment is zero
H2 is linear
N2 is linear
SO3 is linear. resultant dipole moment is zero
CCl4 is tetrahedral; resultant dipole moment is zero
CS2 is linear
