Equatorial FSF bond angle is less in SF4 than in SOF4 since lone pair repulsion is morethan two electron pairs in double bond In both SF4 and SOF4 the hybridisation state of S is same sp3d The OCF bond angle on COF2 is more than 120° since two electron pairs in double bond repel more than one electron pair in C-F bonds. Due to repulsion by lone pair the axial FSF bond angle is less than 180°
