also tell 4 uses of addition reactions in our daily life
Answers
The following three rules can be used when working with addition reactions.
Addition reactions are associated with unsaturated compounds. An unsaturated compound is a compound that contains double or triple bonds. Always, always, remember that you will most likely encounter an addition reaction when your starting compound, or reactant, is unsaturated.
When completed, addition reactions lead to a single compound, which is the final product. What you won't find are any leftovers or doggy bags. In chemistry, leftovers are called residues. Addition reactions will not have any reactant residues on the product side.
Atoms can only be added to molecules when forming a product; nothing is eliminated or taken away. Remember that addition reactions involve the addition of an atom to a compound containing a single or double bond. Whatever the scenario, adding atoms or combining reactants, addition reactions will never involve the elimination or removal of atoms or molecules.
Now that we know the rules, let's look at an example of an addition reaction.
Examples
In organic chemistry, the most common use of addition reactions involves alkenes. Alkenes are molecules consisting of hydrocarbons (hydrogen + carbon) and double bonds. As alkenes have double bonds, can you guess what kind of compounds they are? If you just said, 'unsaturated compound,' you're correct!
