Question

For the IBr molecule, how many electrons occupy the MO sketched here? Express your answer as an integer.

A) 12
B) 14
C) 16
D) 18

Answer 1

The IBr molecule has 14 electrons occupying the MO sketched here.

Step-by-step explanation:

The IBr molecule has a total of 14 electrons occupying the molecular orbital (MO) sketched here. Each iodine (I) atom contributes 7 electrons, and there is one negative charge, resulting in a total of 14 electrons. The Lewis electron structure of IBr would be represented as:

I-Br
