Ethane is an alkane having two carbon atoms bound to hydrogen atoms. Recall what you have learned about the tetravalent nature of carbon and predict the chemical formula of this molecule.
The molecule for ethane is C2H6. or CH3-CH3. Carbon LOVES hydrogen. If possible, Carbon would have four bonds attach to hydrogens. IN this molecule, one of the bond is used to attach a carbon to another carbon, so instead of 4 hydrogens, each carbon would have 3 hydrogens..
