Question

formation of phosphorous tri chloride single co valent bond
​

Answer 1

As we know It needs one electron to make it stable at 8 electrons in its valence shells. This makes chlorine a Cl−1 anion. ... Three Chlorine atoms will each share the unpaired electrons with the three unshared electrons on the Phosphorus. The resulting shared electron bonds form a compound of Phosphorus trichloride or PCl3 .
