What features characterize an alkene?

Answer 1

1. They are saturated hydrocarbons linked by single bonds.

2. The formula is CnH2n+2

3. The C bonds are very stable and difficult to break

The reaction that they have is known as free radical substitution with halogens in the presence of sunlight and combustion. They also react with a nickel catalyst to give out hydrogen.

Answer 2

Alkanes are saturated hydrocarbons such as methane, ethane and propane. Some advantages of using these compounds are: they provide an excellent fuel, are great lubricants and are antiseptic.

Answer 3

An alkene is an unsaturated hydrocarbon that contains at least one carbon-to-carbon double bond.

Answer 4

A carbon to carbon double bond, which is a type of bond formed by sharing four electrons between only two carbon atoms.

Answer 5

they have single bonds

Answer 6

Alkanes are saturated hydrocabons.
