Expert Answer
1) Which one among PCl4+ and PCl4- is not likely to exist?
Ans: PCl4+ exists more likely than PCl4-.
As we move down the group the stability of +5 oxidation state decreases and the stability of +3 oxidation state increases.
PCl4+ is more stable as it has +5 which is more stable.
2)
3)
4) In H3PO2, two hydrogen atoms are bonded directly to the phosphorous atom which imparts the reducing character to the acid.
5) PCl5 has trigonal pyramidal structure and the three equatorial P-Cl bonds re equivalent, while two axial bonds are different and longer then equatorial bonds.
On heating, PCl5 breaks down into phosphorous trichloride and chlorine gas, which shows that out of five P-Cl bonds three are equatorial and tightly bonded and two are axial which are weak bonds hence breaks.
