How can you tell if something is alkane or alkene?

Just so, how can you distinguish between alkenes and alkyne?
- Alkenes and alkynes are named by identifying the longest chain that contains the double or triple bond.
- The chain is numbered to minimize the numbers assigned to the double or triple bond.
- The suffix of the compound is “-ene” for an alkene or “-yne” for an alkyne.
Also, what two solutions can we use to test for alkenes? This allows us to tell alkenes apart from alkanes using a simple chemical test. Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot.
Considering this, is alkane or alkene more reactive?
Alkenes are relatively stable compounds, but are more reactive than alkanes because of the reactivity of the carbon–carbon π-bond. Most reactions of alkenes involve additions to this π bond, forming new single bonds.
How can you distinguish between alkane alkene and alkyne?
Alkanes are saturated hydrocarbons; meaning a single bond between the carbon atoms; alkenes are unsaturated hydrocarbons meaning one or more double bonds between carbon atoms; alkynes are also unsaturated hydrocarbons with one or more triple bonds between the carbon atoms.
