Question

in pcl5 bond angle in plane is​

Answer 1

Answer:

90 degrees.

Explanation:

cause it is mentioned as planar angle

Answer 2

120∘  and  90∘

According to the VSEPR theory,

• PCl is the bonding environments & forms two bonds in this  PCl5 molecule.

• The central atom is P & it contributes  the 5 electrons.

• There are 5 Cl to bond with P. So 5 Cl are contributing the total of 5 electrons.  P & Cl contribute the total 10 electrons. The geometry of PCl5 is the trigonal bipyramidal.

• Each of the two P−Cl bond makes two 90∘ and two 120∘ bond angles with  other bonds in the molecule.

• We must remember that  axial to  three equatorial bonds, so one axial bond is at right angle to the 3 bonds. Thus, 2 axial bonds will be at  right angle to 6 bonds. So,  number of right angles is the 6.

• Each of the equatorial PCl5 makes the two right angles.  Mixing of ones, three P & one d atomic orbitals to form the five sp3d hybrid orbitals of equal energy is called the sp3d hybridization.

Hence the answer is   120∘  &    90∘   .
