Single and triple
The carbon "skeleton" has one double bond, the rest are single bonds
Alkanes have a single bond, and Alkenes have a double bond. The general form for Alkenes is CnH(2n)
Single and double
No, in aromatic compounds and some aliphatic compounds have deloclized pi bonds but in most of the alkenes and alkynes there are localized pi bonds.
KMnO4 will add across the double bond of alkenes (or alkynes) resulting in the docolouring of KMnO4 but not an alkane such as ethane.

Alkenes are hydrocarbons containing carbon-carbon double bonds. There are several different names for alkenes. Some examples are butane, pentene and octadiene.
Olefins or alkenes
alkenes
Single and double
An alkene has a double bond between its carbon atomsE.g H2C=CH2 This is an ethene molecule, the simplest of alkenes.
No, in aromatic compounds and some aliphatic compounds have deloclized pi bonds but in most of the alkenes and alkynes there are localized pi bonds.
KMnO4 will add across the double bond of alkenes (or alkynes) resulting in the docolouring of KMnO4 but not an alkane such as ethane.
No, they are unsaturated as they contain double bonds
The difference between an alkane and an alkene is that: Alkanes have only single bonds between carbon atoms and are said to be saturated: when put in bromine water, the bromine water stays orange - formula: CnH2n+2; Alkenes: have one or more double bond(s) between carbon atoms and are unsaturated: when put in bromine water, the bromine water turns clear - formula: CnH2n.
Alkanes have ordinary covalent single carbon-carbon bonds and carbon-hydrogen bonds. Alkenes have double carbon-carbon bonds.
