Natural gas is a molecular compound, mostly methane, CH4. Ethane, propane, and butane are also frequently used as fuels and are gases at room temperature (I assume this is what you mean because any molecular compound exists in a gaseous phase at the correct temperature and pressure). These are all alkanes, the simplest type of organic compounds.
Carbon dioxide is a common molecular compound that is a gas at room temperature.
Liquids (as well as solids to a much lesser extent) have a vapor pressure, and hence are partially dissociated as gases in the air around us all the time. There are gaseous water particles in the air.
Whenever you smell something, a gaseous molecule (which may have vaporized) travels through the air and into your nose and triggers the chemoreceptors in your olfactory receptors. Think of all the solids that you can smell from a distance, and realize that a tiny amount of it has vaporized and is in its gaseous form in the air. [[The ability for this to occur is usually called volatility, but the notion that only volatile compounds can be smelled has recently come under attack.]]

What evidence is there ionic compounds exists as ions in their pure state while molecular compounds exist as molecules in their pure state?
Ionic compounds conduct electricity while molecular compounds do not
How can molecular compounds be distinguished from ionic compounds?
Many ionic compounds exist as crystals but covalent compounds as molecules (there are exceptions as diamond though). Ionic compounds would be good electrical conductors unlike molecular compounds.
Can molecular compounds exist as separate molecules due to covalent bonding?
yes it can
Organic compounds exist as discrete molecules with much weaker intermolecular forces than those seen in ionic compounds?
Organic compounds exist as discrete molecules with much weaker inter molecular forces than those seen in ionic compounds?
Why elements and all compound exist as molecules?
All elements and all compounds do not exist as molecules. As examples, noble gases exist as individulal atoms and ionic compounds form lattices.

yes it can
Is Compounds that are similar to water in molecular mass all exist as solids true or false?
False

Why is all compounds molecules?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
Is PCl you binary molecular compound?
The compound PCl don't exist; all phosphorous chlorides are binary compounds.
Can electrons exist in a covalent compound in an unpaired state?
Yes, some molecular compounds such as nitrogen dioxide (NO2) contain unpaired electrons.
Which compounds do not exist in independent molecular form?
Because u cant bakwas band get out u bandra bandri ya phir bandarya 🐵🐒

Would ionic or covalent molecules use the molecular formula Why?
Covalently bonded compounds are characterized by a molecular formula, because such compounds exist in the form of discrete molecules, all of the atoms of which move together as kinetic-molecular units. Ionically bonded compounds do not have molecules in this sense: Their compounds are made up of at least two kinds of ions, one positive and the other negative, and the ions in these compounds can move separately as kinetic-molecular units: If a positive ion is separated from the particular negative ion with which it was most closely associated initially in a fluid mixture, usually a solution in an ionizing solvent, of both kinds of ions, another negative ion with the same properties is always close by.
