What type of reaction is exhibited by alkenes?
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 formaldehyde undergo addition reaction?
Formaldehye is H2C=O and has a double bond. The Carbon-oxygen bond is slightly polar and the carbon has partial positive charge and oxygen slightly negative charge. Hence formaldehyde will undergo nucleophilic addition addition reaction across the C=O.
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.
A reaction of a hydrocarbon in which carbon dioxide and water are produced is classified as a?
combustion reaction!
Does propane undergo addition reaction?
Alkanes like (methane, ethane, propane etc.) … They do not undergo addition reactions

Where you get Maharastra SET question paper?
Benzene undergo substitution reaction rather than addition?
What forms of energy are present in firevood?
Hydrocarbon compounds, that will undergo a combustion reaction (with O2) that is exothermic (produces heat). It is all potential energy until the reaction is started (activated with some kinetic energy in the form of heat...a flame).
What is the color of aqueous bromine after addition of the hydrocarbon?
red after adding hydrocarbon its blue
How does combustion differentiate between saturated and unsaturated hydrocarbons?
The primary difference is that an unsaturated hydrocarbon contains a C=C double bond allowing it to undergo addition reactions. Saturated hydrocarbons contain only C-C single bonds so only substitution and elimination can occur. The difference can be seen experimentally as an unsaturated hydrocarbon (eg ethene) will decolourise bromine water.

What forms a combustion reaction?
A hydrocarbon and oxygen
Where are all the products of a hydrocarbon combustion reaction?
The products of the hydrocarbon combustion are water and carbon dioxide.
What two reactants are necessary in order for a hydrocarbon combustion reaction to take place?
Hydrocarbon and fuel
