Well if you are referring to the general method to "synthesize" an alkyne, then the easiest way lets say you want ethylene ("ethyne"), the simplest two carbon alkyne, it would be obtained from adding KOH @ 200 degrees Celsius to 1,1-dibromoethane. The result is an internal alkyne, thus ethylene. In case you wanted an external alkyne you would the use NaNH2 @ 150 degrees Celsius. That is just basic, for it could get more complicated!!!
Actually all hydrocarbons are not alkynes, but all alkynes are hydrocarbons. Alkynes contain carbon and hydrogen and hence they are known as hydrocarbons.
No, all alkynes have at least one Carbon-Carbon TRIPLE bond. Alkenes have one double bond.
Unsaturated hydrocarbons are alkenes and alkynes.
Alkanes alkanes and alkynes
1)Bromine solution in carbontetrachloride is used to identify alkanes, alkenes and alkynes. alkanes don't react therefore the color remains as it is ie, brown while alkenes and alkynes react and therfore brown color disappears. 2)Ammoniacal cuprous chloride when reacted with alkanes alkenes give no precipitate while with alkynes give red precipitate. Thus, alkanes with no reaction and unsaturation can be identified from the first test while alkynes from second test. combustion test solubility test kmno4 test sulfuric acid test

What is the general method of preparation of silicides?
Terminal alkynes can form acetylides.
There are more than two methods to prepare alkynes, but for example you can do a double elimination reaction by way of E2 (double dehydrohalogenation), a more direct way and using one reaction only you can use KOH @ 200 degrees Celsius for a central alkyne, or NaNH2 @ 150 degrees Celsius for a terminal alkyne.
Alkanes, Alkenes, and Alkynes are all hydrocarbons. Alkanes are saturated hydrocarbons with single bonds and a general formula of CnH2n+2 (general formula for cycloalkanes is different) Alkenes are hydrocarbons that have the general formula CnH2n and contain a carbon-carbon double bond. Alkynes are unsaturated hydrocarbons containing a carbon-carbon triple bond with general formula C2H2n-2 so that's how they're different. The super obvious thing that makes them similar is their IUPAC nomenclature. That's the basics of it.
An alkyne is an organic compound. An alkyne carbon chain has a triple bond. There are many many different alkynes. I recommend researching 'alkyne' on Wikipedia or somewhere.
