Answer:
polar covalent bonds
Explanation:
Phosphorus trichloride is a chemical compound of phosphorus and chlorine, having the chemical formula PCl 3. It has a trigonal pyramidal shape, owing to the lone pairs of electrons on the phosphorus atom.
Chlorine is more elctronegative than phosphorus . Phosphorus has a lone pair of electrons and every chlorine atom has three pairs of electrons . The molecule is not symmetrical as the shared electron pairs are closer to the chlorine atoms than the phosphorus atoms , the chlorine atoms are shifted towards one side of the center of the molecule , thus a net dipole effect is created. This is the reason why the molecule is polar .
It glow, so light energy go out of the system, exotermic
I will have to say that this statement is true
ones that are answered through observing :)
