One compound that contributes to the "seashore smell" at beaches in hawaii is dictyopterene d', a component of a brown edible seaweed called limu lipoa. hydrogenation of dictyopterene d' with excess h2 in the presence of a pd catalyst forms butylcycloheptane. ozonolysis with o3 followed by (ch3)2s forms ch2(cho)2, ohcch2ch(cho)2, and ch3ch2cho. what are possible structures of dictyopterene d'?

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
