Question
Out of the following chemical species, how many are strictly NON-POLAR ($\mu_{net} = 0$)? $CO_2$, $H_2O$, $CCl_4$, $CHCl_3$, $BF_3$, $BeF_2$, $NH_3$, $NF_3$, $XeF_4$, $PCl_5$.
Answer: 6
💡 Solution & Explanation
A molecule is non-polar if it has a completely symmetrical geometry where all bond dipoles and lone pairs cancel. The non-polar molecules in the list are: $CO_2$ (linear), $CCl_4$ (tetrahedral), $BF_3$ (trigonal planar), $BeF_2$ (linear), $XeF_4$ (square planar), and $PCl_5$ (trigonal bipyramidal). Total = 6.
