TTT
Explanation:
1) S1 : In SnCl2 the bonding takes place in ground state and the bond angle Cl−SnCl is slightly less than 120∘. ... S3 : In SF4, hte bond angles instead of being 90∘ and 180∘ are 89∘ and 177∘ respectively due to the presence of a lone pair.
2) Xef5 molecular geometry
Pentagonal bipyramidal molecular geometry
Examples IF7, ZrF73−
Point group D5h
Coordination number 7
Bond angle(s) 90°, 72°
3)SF 4
has a trigonal bipyramidal structure with a lone pair of electrons at equivalent positionF−S−F bond angle is less than 120o
, in the planer structure the angles are less due to the bulky nature of the lone lone pair. So the angles likely are 89o
and 117o
