which chapter should I complete before start 11th organic chemistry
Hey there
for organic chemistry of class 11 you will find that it starts from the basics itself like general organic chemistry. If you have little prior knowledge of atoms and reactions which i guess starts from first chapter then you will find organic chemistry easy. also knowledge of periodic table is required in small extent. After you complete your GOC you will be having basics of organic and can move to hydrocarbons etc.
good luck
