2B.1 Part B

Postby Rachel Yoo 1F » Tue Oct 30, 2018 11:25 pm

The question asks to draw the lewis structure for COCl2. I drew mine and put oxygen in the middle but when I checked the answers carbon was the central atom. How would you be able to know this?

I believe it is because carbon has the lowest ionization energy, and the atom with the lowest ionization energy is generally the central atom because it shares its electrons more readily.

Oxygen is the element with the second-highest electron affinity/electronegativity so you would almost never put it in the center.
