Direction of Dipole Moment: ${ CH }_{ 3 }F$ and ${ CHCl }_{ 3 }$


Below are 3-dimensional Lewis structures of ${ CH }_{ 3 }F$ and ${ CHCl }_{ 3 }$.

Created for Copyright 2016. All rights reserved.

Use the Lewis structures to help determine which of the following statements are true.

Select ALL that apply.


Both molecules are polar.


Both molecules have a dipole moment.


The dipole moment of ${ CH }_{ 3 }F$ lies along the C-F internuclear axis while that of ${ CHCl }_{ 3 }$ lies along the C-H internuclear axis.


Given the orientations illustrated in the sketch, the dipole moments of each point in opposite directions along the C-F and C-H axes in the respective molecules.
