Question 4

During the processing of natural gas, small quantities of carbonyl sulfide (COSCOSCOS) are often produced as an impurity.

Given the electronic configurations:

  • Carbon: 2.4
  • Oxygen: 2.6
  • Sulfur: 2.8.6

Draw a dot and cross diagram for a molecule of carbonyl sulfide (COSCOSCOS). Show outer shell electrons only.
