How many electron pairs are shared between carbon atoms in a molecule that has the formula C₂H₄?

Question

Quizplus · Accepted Answer

The formula C₂H₄ represents a molecule of ethene (also known as ethylene). Each carbon atom forms three sigma bonds. One sigma bond is formed between each carbon atom and two sigma bonds are formed with two hydrogen atoms. Therefore, each carbon atom shares two electron pairs with its neighboring carbon atom, resulting in a total of 4 shared electron pairs or 2 sigma bonds.
