Question

Which one of the following is the likely bond angles of sulphur tetrafluoride molecule?

(a) 120°, 80° 

(b) 109°, 28 

(c) 90° 

(d) 89°, 117°

Answer 1

(d) 89° , 117°

Normal bond angle in regular trigonal bipyramidal are 90° and 120°. Due to l.p – b.p repulsion, bond angle is reduced to 89° , 117° option (d).
