Question

number 90degreses molecules spresent in PCL5​

Answer 1

PCl₅ Molecule Hybridization: Sp³d hybridization

Shape of molecule: Trigonal Bipyramidal geometry

Five P-Cl sigma bonds are formed.

three of 5 P-Cl bomds lie in one plane at an angle of 120⁰ to one other called as Equatorial bonds.

Other 2 P-Cl bonds are at right angle to the plane of equitorial bonds that is one above and one below the plane. These are called as axial bonds.

as one axial bond is at right angle to 3 equitorial bonds.

then 3 axial bonds will at right angle to 6 equitorial bonds

∴no. of right angle=6

Answer 2

PCl5 molecule hybridization: sp3d hybridization

shape of this PCL5 is trigonal bipyramidal geometry

therefore number of right angles is equal to 6
