What is the Structure of an Ethane Molecule?
A carbon atom has 4
electrons in its
Carbon is in group 4 of the periodic table.
A hydrogen atom has 1 electron in its outer shell.
Hydrogen can only form 1 bond.
The six hydrogen atoms will
their 1 electron with carbon
to form six carbon - hydrogen covalent bonds.
The two carbon atoms will each share
their 1 electron to form one carbon - carbon
covalent bond and make an ethane molecule (C2H6).
The pairs of shared
electrons between the
hydrogen and the carbon atoms
show single covalent bonds - see covalent bonding.
Ethane is commonly represented by the structural formula
where the single lines between
represent single covalent bonds.
