What is Addition reaction?
In [[organic chemistry]] an '''addition reaction''' happens when two [[molecule]]s come together to make a bigger one.<ref>{{cite book |last=Morrison |first=R. T. |last2=Boyd |first2=R. N. |title=Organic Chemistry |url=https://archive.org/details/organicchemistry04morr |edition=4th |location=Boston |publisher=Allyn and Bacon |year=1983 |isbn=0-205-05838-8 }}</ref> This can only happen when one of the molecules already has a [[double bond|double]] or [[Triple bond|triple]] bond. These can be [[carbon]]-carbon bonds or even carbon-[[oxygen]], carbon-[[nitrogen]] and others. One of the two molecules is called the [[nucleophile]], and this is the one that gives the [[electron]]s to the other to make the new bond. The other molecule is called the [[electrophile]], and this is the one that gets the electrons. An addition reaction is the opposite of an [[elimination reaction]]. Common examples of addition reactions are the addition of [[water]] across a double bond and the nucleophilic attack on a [[carbonyl]].
