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 else can I help you with?
Can molecular compounds exist as separate molecules due to covalent bonding?
Yes, molecular compounds are formed through covalent bonding where atoms share electrons to form molecules. These molecules can exist as separate entities due to the strong bonds between the atoms.
What evidence is there ionic compounds exists as ions in their pure state while molecular compounds exist as molecules in their pure state?
Oh, dude, so like, ionic compounds are made up of ions, which are like charged particles, so they exist as ions in their pure state. And molecular compounds are made up of molecules, which are like groups of atoms held together by chemical bonds, so they exist as molecules in their pure state. It's like, basic chemistry, man.
Which compounds do not exist in independent molecular form?
Ionic compounds such as sodium chloride (NaCl) and metallic compounds like steel do not exist in independent molecular form. These compounds are made up of ions or atoms arranged in a lattice structure, rather than discrete molecules.
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.
Is it true that a Covalent compounds exist only as crystalline solids at room temperature?
No, covalent compounds can exist in various physical states at room temperature, not just as crystalline solids. They can also be found as liquids or gases depending on their molecular structure and intermolecular forces. Examples include water (liquid) and methane (gas).
Is Compounds that are similar to water in molecular mass all exist as solids true or false?
False. Compounds that are similar to water in molecular mass can exist in various states of matter depending on their chemical properties. For example, compounds like ethanol and methanol, which have similar molecular masses to water, can exist as liquids at room temperature.
Can molecular compounds exist as separate molecules due to covalent bonding?
Yes, molecular compounds are formed through covalent bonding where atoms share electrons to form molecules. These molecules can exist as separate entities due to the strong bonds between the atoms.

Why are molecular compounds not written always written in their lowest ratio?
Molecular compounds are not always written in their lowest ratio because the ratio may not simplify further without changing the identity of the compound. Additionally, different ratios can exist due to isomers, which are compounds with the same molecular formula but different structural arrangements.
Which compounds do not exist in independent molecular form?
Ionic compounds such as sodium chloride (NaCl) and metallic compounds like steel do not exist in independent molecular form. These compounds are made up of ions or atoms arranged in a lattice structure, rather than discrete molecules.
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.
What phases of matter would you most likely to find molecular compounds?
Molecular compounds are most commonly found in the solid and liquid phases of matter. In the solid phase, they typically form crystalline or amorphous structures, while in the liquid phase, they exist as discrete molecules interacting through intermolecular forces. Some molecular compounds can also exist in the gaseous phase under certain temperature and pressure conditions, but they are less stable as gases compared to ionic compounds.
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 electrons exist in a covalent compound in an unpaired state?
Yes, electrons can exist in a covalent compound in an unpaired state. This occurs in compounds with odd numbers of valence electrons or when unpaired electrons are involved in bonding. Examples include free radicals like nitric oxide (NO) or oxygen (O2).
The properties of both ionic and molecular compounds are related to the?
The properties of both ionic and molecular compounds are related to their chemical bonding. Ionic compounds have strong electrostatic interactions between positively and negatively charged ions, resulting in high melting points and conductivity when dissolved in water. Molecular compounds have covalent bonds between atoms and tend to have lower melting points, are usually not conductive, and can exist as gases, liquids, or solids at room temperature.
What Compounds can exist in liquids and solids or gases?
Compounds that can exist in all three states of matter (liquid, solid, gas) are called volatile compounds. Examples include ethanol, water, carbon dioxide, and ammonia. These compounds have varying boiling and melting points which allow them to exist in different states under different conditions.
