Question

Question 10 1 pts Consider the Lewis structure of IF7, what is the bond angle between F-I-F? <1200 1800 1200 109.50 <109.50

Answer 1

I has 7 valence electrons.

Due to -1 charge it has 8 valence electron.

2 are used to form 2 bonds.

Remaining 6 electrons are present as 3 lone pairs.

Central atom has 3 lone pair and 2 bond pair

So, the shape is Linear

That is both F will be directly opposite to each other above and below the horizontal plane.

So, FI-F bond angle will be 180 degree.

3 lone pairs will be in the plane in trigonal planar geometry.

Answer: 180
