Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.

When alkenes undergo addition reaction what kind of bond does it produce?
Single bond
How bromine water can be used to test for an alkene?
Alkenes, or hydrocarbons with at least one double bond undergo an addition reaction when combined with bromine (Br2). The general reaction is H2C=CH2 --> H2BrC--CBrH2, and it occurs readily. This reaction is a good way to identify alkenes because bromine has a reddish color, while alkanes and alkenes are colorless. So if bromine is added to an unknown hydrocarbon, the disappearance of the color is an indication of the presence of a pi bond.
Why are alkane called olefins?
Alkenes are also called OLEFINS because they form oily liquids on reaction with chlorine gas.
What type of compound react with ozone?
Compounds that contain double or triple bonds, such as alkenes or alkynes, can react with ozone. This reaction results in the breaking of the double or triple bond and the formation of oxygen-containing compounds. This reaction is commonly known as ozonolysis.
Why are alkenes from alcohols not used on an industrial scale?
Since alcohols are obtained by hydration of alkenes, it is meaningless to manufacture alkenes from alkanes. Moreover, cracking hydrocarbons is a more effective and economical to make alkenes. Shawkat

What type of bonds do Alkenes always have?
Single and triple

Who found alkenes?
Zoe alkenes found alkenes
C2H4 plus H2O equals?
This reaction is an example of a 'hydration' or 'addition' reaction of alkenes: (ethene + water) C2H4 + H2O --> C2H5OH (ethanol) The reaction is catalysed by H+ ions (acid)
What type of reactions do saturated hydrocarbons undergo as opposed to unsaturated hydrocarbons?
Subistitution reaction: It's a reaction where the bonds of unsaturated alkenes (double bond) can be broken down and substituted by other elements, which replace hydrogen bonds. Also they will form only a single bond.
Why does the bromine dissolved in carbon tetrachloride is not used to differentiate between alkenes and alyles?
CCL4 is a carrier for Bromine reaction.

What is the type of symmetry exhibited by echinoderm larvae?
Bilateral symmetry :)
What type of geometry is exhibited by a matchbox?
A matchbox is a cuboid or hexahedron.
What type of bonds do alkenes have?
The carbon "skeleton" has one double bond, the rest are single bonds
