Question

Which has zero dipole moment?

• A. $ClF$
• B. $P{Cl}_3$
• C. $Si{F}_4$
• D. $CF{Cl}_3$

Answer 1

Answer: (C)

$Si{F}_4$

$Si{F}_4$ has zero dipole moment.It possess regular tetrahedral geometry.The silicon-fluoride bonds are dipoles and these individual bond dipoles cancel out to give a net zero dipole.
