PAGE 1 Formula Four Calculating yield of poroduct Peak aguea of one beak * 100 Sum of peax goreas · Boiling point of hept-1-ene = 93.6°C hept - 2-ene = 98-5°C hept - 3- Che = 94.3°C Given Gax chriomatograph is fogt hept-1-enc, Hence its Agea beacenfage 91,2359% Area 45944,1523. Higher the boilëng bounty lower will be its volatile character Hence hebt-2-ene comes at last in ac. u Hebt-1-ene (93.6°C) - Hept-2-ene. (98.5°C) Hept-3-the (94,3°C)
