The branch of the natural sciences dealing with the composition of substances and their properties and reactions.This was the definition I came to know when I was in VIth Standard and got an impression that it is an interesting subject.But today as I am doing my MSc in Chemistry,truly speaking the interest I was having towards this subject is totally lost.I am fed up with the subject.
Recently,while I was preparing for my exams,I found a word called '3,7 dimethylcyclopentanophenantherene'...Damn this word is bigger than sentences I write.I took a stopwatch and started reading the word again.Seriously it took me seven seconds to reach to the end of the word.And after that there was one way and that was to close the book and sleep.And I did that without any hesitation.But the next day I daringly took the step of going through the word again and came to know that its nothing but the positions of methyl group in cholesterol i.e.,its a cholesterol structure where four cyclohexane rings are attached to each other and two methyl groups are attached to it in position 3 and 7 respectively.And later when I stepped into the synthesis part of cholesterol believe me the entire mechanism comprised of seven pages.Initial step consists of one closed ring with two methyl groups and one phenol.And finally after various experimental methods it was converted to four closed rings and one opened ring with one OH-group attached to it.And this is called cholesterol whose molecular formula is C27 H46 O. We know that its harmful to a human body if the cholesterol level is high but I would say its more harmful if we go through the theoritical study of cholesterol.And finally when I completed this chapter my brain had reached its melting point and I again went to sleep.
What I wrote above was about cholesterol only.But that was not the end,there were more products that sucked me.They are Alkaloids, Quinine, Respirene, Terpenes, Alpha-pinene, Camphor, Oestrone, Equilenin and more...
But again today in the morning while I was going through wikipedia I found an attractive product called Aerogel . Aerogel is a solid state material with the lowest known density.There are various kinds of aerogel like silica-aerogel,carbon-aerogel,allumina-aerogel.
The above pictures are different forms of aerogel.See how a 2.5kg brick is supported by a piece of aerogel weighing only 2 gms.After going through the article I realised that I am lucky to have this subject and should take more interest towards this.
