  1. ESTERIFICATION H H H H O H O OH H H H H H H H H H H H H H H H H O THE DOTTED WHITE LINE SHOWS WHERE THE NEW BOND FORMS C C C C C PROPANOIC ACID ETHANOL O C C C C C + HOH ESTER LINKAGE ESTERIFICATION IS AN EXAMPLE OF DEHYDRATION SYNTHESIS, WATER IS REMOVED, IS A PRODUCT ACID PART ALCOHOL PART ALCOHOL PART ACID PART ETHYL PROPANOATE

  2. ADDITION (ALKENE) H H H H H H H H H H H H H H H H H H Br H H H Br Br H H H Br 2-BUTENE (CNH2N) BROMINE REMEMBER EACH C HAS 4 BONDS, EACH H ONLY 1, EACH HALOGEN ONLY 1 + Br2 C C C C ! REMEMBER: The halogen MUST bond to carbons where the double bond was located 2,3 DIBROMO BUTANE SAME AS C C C C C C C C ! 2,3 DIBROMO BUTANE, THESE STRUCTURES ARE NOT ISOMERS, THEY ARE THE SAME, THE SINGLE BOND ROTATES.

  3. ADDITION (ALKYNE) H H H H H H H H H H H H H H H Br H H H Br Br Br 2-BUTYNE(CNH2N-2) BROMINE + Br2 C C C C THE CIS AND TRANS ISOMERS ARE NOT INTERCHANGEABLE, THERE IS NO ROTATION OF DOUBLE BONDS 2,3 DIBROMO BUTENE + C C C C C C C C CIS ISOMER TRANS ISOMER
