Answer» SISTS of different types of P-Cl bonds: i) Axial bonds (two chlorine atoms bonds with P axially) ii) Equatorial bonds (three chlorine atoms having bond length equi-distant from P) iii) It is known that axial bonds are LONGER than equatorial bonds. iv) Due to unequal bond lengths between axial and equatorial bonds, is unstable and highly reactive. V) STRUCTURE of is as FOLLOWS,
