AlkAnes are any hydrocarbons that have single C-C covalent bonds . e.g. Ethane, or propane to name but two.
Structurally ethane is H3C-CH3
Do Not confuse with
AlkEnes and AlkYnes
Alkenes are hydrocarbons that have at least one pair of carbons with a double (C=C) covalent bond between them. e.g. Ethene , Propene to name but two .
Structurally, ethene is H2C=CH2
Alkynes are hydrocarbons that have at least one pair of carbons with a triple (C///C)covalent bond between them. e.g. Ethyne(acetylene), Butyne. to name but two.
Structurally ethyne is HC///CH
Note the reduction in hydrogens for each additional covalent bond.
Be careful when writing the names. There is only ONE letter difference between functional groups. viz. 'a', 'e' or 'y'.
Any number of chemical moieties could react with alkanes to produce new compounds in a substitution reaction. For example, hydrohalic acids (HCl, HBr, HI) could react with an alkane to produce a haloalkane. Here, the halogen atom would replace one of the hydrogen atoms in the alkane. (HCl + ethane --> chloroethane) (HBr + propane --> bromopropane) This also works with other reactive species, such as: - nitric acid + alkane --> nitroalkane
it is an example of an alkane (with four carbon atoms)
In an alkane, each carbon atom is bonded to 4 hydrogen atoms. So, the number of hydrogens in an alkane can be determined by the formula 2n+2, where n is the number of carbon atoms in the alkane.
Yes. The alkane series is the series of saturated hydrocarbons with the formula CnHn+2 .
The IUPAC name for the alkane given is the systematic name assigned to the specific alkane based on its structure and number of carbon atoms.
No. An alkane is a compound of carbon and hydrogen. Carbon monoxide consists of carbon and oxygen.
methane, ethane, propane, hexane .... these are some of the famous alkanes

No, there are many alkanes; methane is the simplest alkane.
Yes, if the alkane is cyclic and the alkene is not.

No. Octane is an alkane but it has eight carbons.
