The correct answer is: 10
Planar molecules

ClF3,XeF4,H2O, H2S, OCl2, C6H6, I2Cl6, BF3, SO3,XeF2

ClF3 Central atom Cl has 2.lp+3Bp=sp3d hybridised it is T-shape (planar)
H2O Central atom O- has 2lp+2Bp=sp3 hybridised (angular)( planar)
PCl3 Central atom P- has 1lp+3psp3 hybridised pyramidal (non planar)
BF3sp2 hybridised triagonal planar (planar)
SF4CentralatomS has 1lp+4Bp,sp3d hybridised see-saw structure (non planar)
H2SCentralatomS has 2lp+2bp angle between H-SH is 90° (planar)
OCl2CentralatomO- has 2lp+2bp ; angular shape (planar)
SO3sp2 hybridised, triangonal (planar)
XeF66Bp-sp3d2 hybridised/ square bipyramidal (non-planar)
NH31lp+3Bpsp3 hybridised ( pyramidal (non-planar)
C6H6 in benzene all C- atoms are sp2 and planar molecule.(planar)
XeF23lp+2Bp;-sp3d hybridised ,linear shape(planar).
XeF41lp+4Bpsp3d hybridised structure see-saw (non-planar)
PCl55Bpsp3d hybridised TBP (non-planar)
I2Cl6
dimer (planar)
