What has it got to do with other jobs?

It's good when some of the students asked about 'chemistry relations with the other jobs like being a religious teacher. Well, it's quite simple. All the issues like wearing perfumes, or dying hairs can actually help the teacher to solve the problems if he or she has a good knowledge in chemistry..

I'M BACK !

It's been 2 years. Not posting anything in this blog. But I'm back to teach form5 chemistry...  Only this time I love to see my students really having fun in my class.. I bet they do! 

Gasoline ( Petrol )

The petroleum era began in August 1859, when the world's first oil well was drilled near Titusville, pennsylvania.
The petroleum was distilled into fractions according to boiling point, but it was high-boiling kerosene, or lamp oil, rather than gasoline that was primarily sought. Literacy was becoming widespread, and people wanted better light for reading than was available from candles.
Gasoline was too volatile for use in lamps and was initially considered a waste by-product.
The world has changed greatly since those early days, however, and it is now gasoline rather than lamp oil that is prized.

Arenes

In early days of organic chemistry, the word aromatic was used to describe fragrant substances such as benzene( from coal distillate), benzaldehyde( from peaches, cherries and almonds), toluene ( from Tolu balsam).
Aromatic compounds show chemical behavior quite different from the alifatic compounds we have studied to this point.
Many compounds isolated from natural sources are aromatic in part. Steroidal hormone estrone and the well-known analgesic morphine have aromatic rings. Many synthetic drugs are also aromatic in part; the tranquilizer diazepam ( Valium) is an example.
Benzene should be handled cautiously if used as a laboratory solvent because it can cause bone marrow depression and consequent leukopenia( lowered white blood cell count) on prolonged exposure.
