ORGANIC CHEMISTRY Chapter 3 Additions(加成) g Addition reactions occur when two reactants add together to form a single new product with no atoms“ left over? o In an addition all parts of the adding reagent appear in the product; two molecules become one A +B C Br Bi CHo=CHo Br-Br CH -CH, H Br CH2=CH2+H-Br—CH2-Cl Department of Chemistry, Xiamen University
