Methane is the main component of natural gas. Methane in its natural state is found under the sea floor and below the ground.Some of its uses are: cooking fuel, rocket fuel, and to convert water and carbon dioxide into gas.

The chemical notation "CH2CHCH(CH3)CH3" represents the alkane pentane, which has 5 carbon atoms in a straight chain. The molecule is made up of carbon (C) and hydrogen (H) atoms with specific bonds between them, forming a saturated hydrocarbon. In this case, "CH2" represents a methylene group, "CH" a methine group, and "(CH3)" a methyl group.
The molecule C6H12O is likely to be 3-hexanol, which features a hydroxyl group (-OH) and a branched carbon chain. In its 1H NMR spectrum, it exhibits a quartet of quartets due to the presence of a methylene (-CH2-) group adjacent to both a methyl (-CH3) group and a methine (-CH-) group, leading to complex splitting patterns. Additionally, a triplet of quartets can arise from the splitting of protons on adjacent carbons, resulting in overlapping multiplets. This multiplicity indicates the presence of neighboring protons that are contributing to the coupling patterns observed in the spectrum.
Porphyrins are a group of chemical compounds of which many occur in nature, such as in green leaves and red blood cells, and in bio-inspired synthetic catalysts and devices. They are heterocyclic macrocycles characterised by the presence of one pyrroline and three pyrrole chemical groups interconnected via their α carbon atoms via methine bridges (=CH-). Porphyrins are aromatic, and they obey Hückel's rule for aromaticity in that they possess 4n+2 pi electrons that are delocalized over the macrocycle. The macrocycle, therefore, is a highly-conjugated system, and, as a consequence, is deeply colored - the name porphyrin comes from a Greek word for purple. The macrocycle has 26 pi electrons. The parent porphyrin is porphine, and substituted porphines are called porphyrins. Therefore, it appears that you are gravely mistaken with the meaning of porphyrin.
