Is the conversion of an alkene to an alkane a reduction or an oxidation?
The addition of hydrogen on alkenes produces the alkanes so it is a reduction process.
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.
What is the difference between the carbon groups called alkanes and alkenes?
Alkenes have at least one double bond between two carbon atoms; alkanes don't.
When alkenes undergo addition reaction what kind of bond does it produce?
Single bond
Which compound may be formed when alkanes are cracked?
When an alkane is cracked, alkenes and shorter alkanes are produced.
Why alkanes do not react with bromine water?
No, bromine will only add to alkenes, so NO addition reaction to alkanes. Subtitution on alkanes is not possible at standard conditions
Do alkanes react with hydrogen?
Alkanes are not really reactive if you compare them to alkenes or alkines. They don't have double or triple bonds, they only have single bonds between their C-atoms so they aren't as reactive as alkenes or alkines. Alkanes are pretty stable since they don't have clouds of delocalised electrons as arenes do. Typical reactions for alkanes are pyrolysis, oxidation and substitution When it comes to substitution, they can substitute one of their C-atoms with a halogen, and the products of that reaction are halogen-hydrogen and halogenalkane For instance, Butane + Cl2 --> Clorobutane + HCl
What come from crude oil alkanes or alkenes?
alkanes
Is halogenation of alkanes a nucleophlic or electrophlic mechanism?
alkenes are neutral nucleofiles they undergoes electrophilic addition reactions.
How can bromine water test the difference between alkanes and alkenes?
Bromine water can test the difference between alkanes and alkenes because the bromine water turns colourless for the alkenes but doesnt change for the alkanes.
Is the conversion of an alkene to an alkane a reduction or an oxidation?
The addition of hydrogen on alkenes produces the alkanes so it is a reduction process.
What is the difference of alkanes and alkenes?
Alkanes are saturated hydrocarbons. Alkenes are unsaturated hydrocarbons with atleast one carbon-carbon double bond.
What differentiates alkenes from alkanes?
alkanes have single covalent bons, alkenes have double :) lol did this while doing chem homework myself
What are some examples of alkanes and alkenes?
Saturated oils and waxes are all types of alkanes and alkenes The Ice man ;) Call me ladies... ;')

How are alkenes made from alkanes?
cracking maybe?
