I'd think it is diamond (tetrahedral C4)
ionic compound
Carbon dioxide is a compound; therefore, its smallest unit is a molecule.
Polar Covalent
Unsaturated when there is at least one double or triple bond between 2 carbon atoms.
Hydrogen and carbon do not create a new compound by themselves. To create a new compound, they would need to bond with atoms of more elements.
An alkine is a hydrocarbon compound with a carbon-to-carbon triple bond. The smallest possible alkine is saline, which as structural formula HCCH, with the carbon atoms triple bonded.
ionic compound
The smallest molecular compound would probably be hydrogen fluoride, HF.
Double Bond.
The Smallest unit of an covalent bond is a molecule
Carbon dioxide is a compound; therefore, its smallest unit is a molecule.
This compound is carbon tetrabromide.
Type your answer here..carbon
Carbon monoxide is a molecular compound because carbon and oxygen form a covalent bond with one another.
carbon dioxide CO2
This compound doesn't exist.
Carbon is tetravalent. So, it can bond with maximum of four atoms.
