NOTE:
If more than one bond angle is possible, separate each with a space.
For example, trigonal bipyramid geometry can lead to 3 different bond angles.
Octahedral geometry can lead to 2.

Expert Solution

Hi,

A) For BrF5,

The central bromine atom makes five bonds to fluorine and has one pair of electrons for a total of six electron domains. The geometry is square pyramidal and the bromine is sp3d2 hybridized. Counting the electrons around the bromine and examining the orbitals it seems the bromine atom violates the octet rule. It uses its d orbitals to accommodate the extra electrons.

Hybridization: sp³d².

The molecular geometry of BrF5, considering only the atoms, is square pyramidal,hybridisation is sp3d2..... The electron pair geometry around the central atom is octahedral....
because of lone pair-bond pair repulsion bond angle reduces from 90 to 84.8 degrees...

B) For XeCl2

Hybridization: sp³d.

There are 5 pairs of electrons about the central Xe atom. The structure will be based on a trigonal bipyramid geometry. The most stable arrangement of the atoms in XeCl2 is a linear molecular structure with a180

The bond angle in NH3 is significantly smaller than the ideal bond angle of 109.5° because of the lone pair on the central atom. Which best explains why the bond angle in SO2 is very close to 120° despite there being a lone pair on the central atom?

A) Which of the following statements are true? Note that there may be more than one correct answer; select all that are true. As the p-value increases, the evidence against the null hypothesis also increases. In hypothesis testing, if the p-value is sufficiently small, then the null hypothesis can be rejected in favour of the alternate hypothesis. If the null hypothesis is true, then the p-value will always be greater than 0.1. If the null hypothesis is false, then the...
