Assuming you mean hydrogen, you could start with water (H2O).

No, hydrogen is not part of all organic compounds. While hydrogen is commonly found in organic molecules, there are some organic compounds that do not contain hydrogen, such as organometallic compounds or compounds containing only carbon and oxygen.
hydrogen is odorless
Gas
No it is not. Methyl is the CH3 group which is part of some covalent compounds.
Some of it is atmospheric gasses, some of it (often a quite large part) is methane, and a small percentage is other organic compounds. The "other organic compounds" is the part that's responsible for the smell; methane itself is odorless.
New physical properties are some of the items related to compounds.
a couler less gas that burns easily and is the lightest element of the universe
The element that is part of both of the compounds that are not flammable is oxygen. Oxygen is present in various compounds and is not a flammable element itself.
