3.3.4 - alkenes Flashcards
1
Q
what is the general formula of an alkene
A
CnH2n
2
Q
what elements do alkenes contain
A
only carbon and hydrogen atoms, making them hydrocarbons
3
Q
what bonds to alkenes contain
A
alkenes contain at least one C=C double covalent bond
4
Q
are alkenes saturated or unsaturtaed
A
alkenes are unsaturated
5
Q
why are alkenes unsaturated
A
molecules with C=C double bonds are unsaturated as they can make more bonds with extra atoms in addition reactions
6
Q
what feature does the C=C bond in an alkene have
A
as there are 2 pairs of electrons in the C=C double bond, it has a really high electron density
7
Q
are alkenes reactive or unreactive?

alkenes are pretty reactive
