Question

Which do not have zero dipole moment?

• A. ${CS}_2$
• B. $H_{2}O$
• C. ${SO}_2$
• D. ${NO}_2$

Answer 1

Answer: (B), (C), (D)

$H_{2}O$
${SO}_2$
${NO}_2$

$C{S}_2$ has linear shape.It do not have dipole moment.

$S=C=S$ Linear shape(Bioth sides to carbon have same atoms in opposite directions then dipoles cancels between them and makes net dipole moment zero)

Remaining all are having Dipole moment.

Hence option B,C,D are correct.
