Question
Which one of the following pairs of molecules will have permanent dipole moments for both members ?
A.
$$N{O_2}\,{\text{and}}\,C{O_2}$$
B.
$$N{O_2}\,{\text{and}}\,{O_3}$$
C.
$$Si{F_4}\,{\text{and}}\,C{O_2}$$
D.
$$Si{F_4}\,{\text{and}}\,N{O_2}$$
Answer :
$$N{O_2}\,{\text{and}}\,{O_3}$$
Solution :
Both $$N{O_2}$$ and $${O_3}$$ have angular shape and
hence will have net dipole moment.
