Enter the molecular formula for butane, c4h10.
express your answer as a chemical formula.

Butane is from the family of alkanes with –ane as its family name. The but- prefix stands for having four carbon atoms. The C4H10 is the general formula of butane and can also represent other forms or structures of butane. However if the question asks for the molecular formula of butane, think of how many electrons it can share to the hydrogen atom. The carbon atom can share 4 and hydrogen 1.  So if the three hydrogen atoms are attached to the first carbon, the other shared electron is attached to the second carbon. The second carbon atom can accommodate two hydrogen and 1 carbon. The third carbon can accommodate 2 hydrogen atoms and 1 carbon and the fourth carbon can accommodate 3 hydrogen atoms. The molecular formula is CH3-CH2-CH2-CH3.
