In the calculation of the index of hydrogen deficiency, when the elements of Group 6 are found in a formula no correction to the number of hydrogen atoms is needed.

Question

Quizplus · Accepted Answer

The elements of Group 6 (oxygen, sulfur, selenium, tellurium, and polonium) have six valence electrons, and they typically form double bonds with carbon. In the calculation of the index of hydrogen deficiency, double bonds are counted as one hydrogen atom, so no correction to the number of hydrogen atoms is needed when the elements of Group 6 are found in a formula.
