Fill the blank space to complete the text.

Because alkenes contain at least one double bond between carbon atoms, we describe them as compounds.

Explanation

Question 3 of 16

1

The test for ❌ makes use of the addition reaction, and involves adding ❌ water to a sample of hydrocarbon. If an ❌ is present the solution stays orange-brown, but an ❌ will turn the solution colourless. This is because the bromine is added across the carbon-carbon ❌ bond.

Rusting is a specific example of , and requires both air and water for to rust. There are three ways to prevent iron from rusting:
exclusion of (by either using an atmosphere of nitrogen or argon)
exclusion of (by storing with a desiccant)
sacrificial (when a more reactive metal than iron is attached to the object to prevent iron from rusting)
