Problem 39P

Predict the shape, state the hybridization of the central atom, and give the ideal bond angle(s) and any expected deviations for:

(a) BrO3−

(b) AsCl4−

(c) SeO42−

(d) BiF52−

(e) SbF4+

(f) A1F63‑

(g) IF4−

Step-by-Step Solution:
Step 1 of 3

Solution 39P

Here we have to predict the shape, state the hybridization of the central atom, and have to give the ideal bond angle(s) and  expected deviations for the given molecules.

In order to find out the hybridization of central atom and  structure of a molecule we have to know the number of lone pair and bond pair has been surrounded by the central atom. It can be known by Lewis dot structure.  

The following table is necessary to find out the bond angle depends on hybridization.

Step-1

(a) BrO3−

Lewis dot structure of BrO3−

Here the central atom Br is surrounded by 3 bond pairs and 1 lone pair.

Thus it will form 4 hybrid atomic orbitals i.e sp3 hybridization. Structure of the molecule is trigonal bipyramidal. Depending on the hybridization, the ideal bond angle of this molecule is 109.5o but due the presence of one lone pair of electron, its bond angle deviates and the deviated bond angle is 107o .

Step-2

(b) AsCl4−

Lewis dot structure of AsCl4−

Here the central atom As is surrounded by 4 bond pairs and 1 lone pair.

Thus it will form 5 hybrid atomic orbitals i.e dsp3 hybridization. Structure of the molecule is seesaw. Depending on the hybridization, the ideal bond angle of this molecule is 120o, 90o but due the presence of one lone pair of electron, its bond angle deviates and the deviated bond angle is <120o, <90o .

Step-3

(c) SeO42.−

Lewis dot structure of SeO42.−

Here the central atom Se is surrounded by 4 bond pairs.

Thus it will form 4 hybrid atomic orbitals i.e sp3 hybridization. Structure of the molecule is tetrahedral. As there is no lone pairs on the central atom, the ideal bond angle and deviated bond angle remain same or we can say that there is no deviated bond angle. Therefore...
