Work Step by Step

$BCl_3$: it is trigonal planar and even though its bonds are polar, the vectorial sum cancels out to zero. $PCl_3$: it is trigonal pyramidal, the vectorial sum doesn't cancel out. $POCl_3$ and $SCl_2O_2$, both have square planar geometries but their vectorial sums don't cancel out.
