what elements are present in alkanes
In organic chemistry, an alkane, or paraffin (a historical name that also has other meanings), is a saturated hydrocarbon. Alkanes consist only of hydrogen and carbon atoms and all bonds are single bonds.Alkanes (technically, always acyclic or open-chain compounds) have the general chemical formula C n H 2n+2. For example, methane is CH 4, in which n=1 (n being the number of carbon atoms).he simplest isomer of an alkane is the one in which the carbon atoms are arranged in a single chain with no branches. This isomer is sometimes called the n-isomer (n for normal, although it is not necessarily the most common).
