^ Compounds that only contain carbons and hydrogens
CARBON: makes 4 bonds each
HYDROGEN: makes 1 bond each
TO MAKE A HYDROCARBON, hydrogen and carbon atoms REACT to form COVALENT BONDS.
^Covalent bonds < carbon and hydrogen atoms SHARE a pair of ELECTRONS.
^hydrocarbon has only single covalent bonds
^^the name of an alkane ALWAYS ends in -ane
^^^ALKANES ARE SATURATED (have a maximum number of hydrogen atoms per carbon atom
^^^^ The formula for an alkane is CnH2n
^A hydrocarbon has one or more double carbon-carbon (C=C) covalent bonds, it is an alkene
^^Double bonds have TWO SHARED PAIRS OF ELECTRONS
