The formula for C2H6 is CH3-CH3.
Step-by-step explanation:
The given formula C2H6 is the molecular formula depicting the integral number of atoms of combining elements. From this formula, it can confirmed that 2 atoms of carbon has combined with 6 atoms of hydrogen, but the arrangement of these atoms and the bonding between them is unclear from the given formula.
In order to determine the bonding occurring between elements and how the atoms are arranged or bonded with each other, we use structural formula representation. It is known that a single carbon atom that should have four bonds to attain the stable state and each hydrogen atom can share only one electron.
So the structural formula of C2H6 can be written as CH3-CH3. This indicates that three hydrogen atoms will be bonded with a single carbon atom leading to formation of single bond between two carbon atoms surrounded by three hydrogen atoms on either sides of carbon atoms. This material is termed as ethane and it falls in alkalies group of organic compounds.
