Propene, or propylene, is a common type of alkene composed of three bonded carbon atoms.
The molecular formula of the methyl group is CH3. It consists of one carbon atom bonded to three hydrogen atoms.
Propene is the alkene with the formula C3H6. It consists of three carbon atoms and six hydrogen atoms, with a double bond between two of the carbon atoms.
Propane is an alkane. The last syllable of the name indicates this. An alkyne (which contains a triple bonded carbon to carbon link) would end in "-yne" and an alkene (which contains a double bonded carbon to carbon link) would end in "-ene". The first syllable indicates the length of the carbon chain. So "meth-" is a single carbon, "eth-" two, "prop-" three. Therefore propane is a three carbon singly bonded molecule.
Both the choices given are acceptable and correct chemical formulas in most contexts, because each one shows the presence of two carbon atoms and six hydrogen atoms in each molecule. The second formula is preferred in some contexts because it hints at the structural formula of the molecule, which has each hydrogen atom bonded directly to only one of the carbon atoms, and in order to further emphasize this point the formula is sometimes written as H3C-CH3.
The expanded structural formula for an alkane with three carbon atoms is CH3-CH2-CH3, also known as propane. Each carbon atom is bonded to the appropriate number of hydrogen atoms.
The chemical formula CH3CH2CH2CH3 represents the alkane butane, which has four carbon atoms in a straight chain with three hydrogen atoms bound to each carbon atom. It is a saturated hydrocarbon with the molecular formula C4H10.
The molecular formula for calcium carbonate is CaCO3. It consists of one calcium atom, one carbon atom, and three oxygen atoms.
Propene, or propylene, is a common type of alkene composed of three bonded carbon atoms.
The molecule is called propane. It is a three-carbon alkane with the chemical formula C3H8.
The molecular formula of the methyl group is CH3. It consists of one carbon atom bonded to three hydrogen atoms.
The IUPAC name for CH3CH2CH3 is propane. It is a three-carbon alkane with the chemical formula C3H8.
The molecular formula of carbonic acid is H2CO3, which consists of one carbon atom, three oxygen atoms, and two hydrogen atoms.
The molecular formula for 1-chloropropane is C3H7Cl. It consists of three carbon atoms, seven hydrogen atoms, and one chlorine atom.
Propene is the alkene with the formula C3H6. It consists of three carbon atoms and six hydrogen atoms, with a double bond between two of the carbon atoms.
The molecular formula for zinc carbonate is ZnCO3. It consists of one zinc atom (Zn), one carbon atom (C), and three oxygen atoms (O) chemically bonded together.
The formula for chloroform is CHCl3, which represents one carbon atom, one hydrogen atom, and three chlorine atoms.
