Question #c8b12

Answer 1

`C_4H_8` is not an Alkane.. It is an Alkene,

Explanation:

You can prove it is an Alkene as it decolourises bromine water from orange/red to colourless. This is a standard test for an Alkene.

Answer 2

No, `C_4H_8` is butene, which is an alkene.

Explanation:

Well, alkenes have a formula of `C_nH_(2n)`, where `n>1, ninZZ`.

To test for alkanes vs alkenes, you have to put their aqueous solutions into bromine water. With an alkane, nothing happens and the bromine water stays brown, while with an alkene, the bromine water becomes colourless as a result of bromine reacting with the double bonds of the alkenes.
