0 a chemical reaction in which two or more substances combine to form a new substance -- 加成反應（兩種或多種物質組合生成一種新物質的化學反應）
The reaction is a form of electrophilic addition; it is similar to the halogen addition reaction.
Two non-polar addition reaction exists as well called free radical addition and cycloadditions.
Kinetic control means that the forward aldol addition reaction must be significantly faster than the reverse retro-aldol reaction.
An addition reaction is the opposite of an elimination reaction.
This nucleophile reacts with the electrophilic alkene 3 to form 4 in a conjugate addition reaction.
The substrate of an electrophilic addition reaction must have a double bond or triple bond.
As a class of addition reaction, cycloadditions permit carboncarbon bond formation without the use a nucleophile or electrophile.
The same is true when an alkene reacts with water in an addition reaction to form an alcohol which involve formation of carbocations.
