because an alkane is a saturated compound, there are no double bonds and therefore the alkane does not replace a carbon-hydrogen bond with a carbon-bromine bond.
An alkene bonds because it is unsaturated, and the carbon-carbon double bond splits, becoming a single bond and forming two new carbon-bromine bonds.

∙ 9y agoAlkanes are unreactive because of their very stable single bonds. These bonds are very saturated and difficult to break, making them almost completely inert.

What are 3 uses of alkanes?
Three uses of alkanes are:used as organic solvents in labs when in liquid formused as a general anaestheticused as fuels because a large amount of energy is released when alkanes undergo combustion.
Why are alkanes unreactive when mixed with acids and alkalis?
I think it's because the covalent bonds are strong, and therefore unreactive to acids & alkalis. You'd need to get alkanes in gas form to make it react, but you'd still need energy for it to react, like, say, heat perhaps?
What Difference between reactivity in hexane and cyclohexane?
Not much. Both are alkanes, and alkanes are highly unreactive. The only reaction for alkanes I can think of off the top of my head is free radical halogenation, but both hexane and cyclohexane have secondary carbons, so reactivity is comparable. Of course, cyclohexane has 6 secondary carbons while hexane only has 4, so you can make the argument that cyclohexane is more reactive in this example.
Are longer chain alkanes more flammable than shorter chain alkanes?
No, Shorter chain alkanes are more flammable
Do alkanes contain phosphorus?
No. alkanes contain only hydrogen and carbon.
Why alkanes called parafins?
because of their unreactive nature alkanes are called parrafins

What are alkanes?
Answer Alkanes are saturated hydrocarbons having a general formula CnH2n+2. Alkanes are unreactive comparing to alkenes, they are not affected by acids or alkalies. But they burn well in a good supply of oxygen, forming carbon dioxide and water vapour. giving out plenty of heat.
Hydrocarbons which have only single bonds between carbon atoms?
All alkanes have single bonds.They consist of single bonds.
How can alkanes be described?
Alkanes can be described as saturated.
Are noble gases reactive or unreactive?
Unreactive
What come from crude oil alkanes or alkenes?
alkanes
Which alkanes are liquid?
pentane and other alkanes above it
