Answer:
Esterification and polymerization
Explanation:
Organic reactions are chemical reactions associated with organic compounds (compounds of carbon).
a) Addition : this is a reaction shown by organic compounds having double or triple bond. On these multiple bonds some other molecules get add on.
so addition is a type of organic reaction.
b) sublimation: it is a physical process where a solid gets directly converted to a gas. Hence it is not an organic reaction.
c) deposition : it is a physical process where something gets deposited over another substance. There is no chemical reaction in this process.
d) saponification: It is an organic reaction, where a fat or oil is heated with NaOH to give soap and alcohol.
e) decomposition: it a chemical process where a large molecule gets decomposed into smaller molecules.
f) esterification: it is reaction of an acid with alcohol to another organic molecule ester. This is organic reaction.
g) polymerisation: it is formation of large macro molecules, by repetitive combination of small molecules. This is an organic reaction.
