Large - think they're C25+
The alkane molecules which have small numbers of carbon are Methane (CH4) Ethane (C2H6) etc - they have lower boiling points and are more useful as fuels etc.
No. An alkane is a compound of carbon and hydrogen. Carbon monoxide consists of carbon and oxygen.
In one molecule of bitumen there are 22-45atoms of carbon.
Propane is the alkane with three carbon atoms.
The number of carbon atoms and therefore size of the molecules (Methane=CH4, Propane=C3H8) PROPANE IS A BY-PRODUCT OF CRUDE OIL REFINING. METHANE IS A GAS THAT WILL COME FROM ANYTHING THAT WILL NATURALLY DE-COMPOSE
No. Octane is an alkane but it has eight carbons.
This alkane is n-octadecane with the chemical formula C18H38.
octet rule
For a straight-chain alkane, this would be C10H22 - decane. However, if this is a cyclic alkane, you would have C10H20 (cyclodecane). There are also numerous options for a branching alkane with various names and carbon to hydrogen ratios.
A non cyclic alkane always has a number of hydrogen atoms equal to 2c + 2, where c is the number of carbon atoms. Therefore, hexadecane, an alkane with 16 carbon atoms, will have 34 hydrogen atoms.
Methane, CH4
the number of carbon dioxide molecules
The generic formula for an alkane is CnH(2n + 2).Therefore, an alkane with 3 carbon atoms would have 8 hydrogen atoms.
