In this final section for organic chemistry for A-level, we will see the chemistry of polymers. This section will discuss the basic principles in polymer chemistry, including type of polymers and polymerisation reaction. This section will be concluded by extension section about inorganic polymers. Synthetic vs Natural Polymers Plastic Bottle vs Antifreeze protein from Tenebrio molitor

Falling in love is one of the greatest gifts to humankind and also it is one of the strongest feeling that human can have. This feeling also quite interesting because every person would have different answer why they are attracted to somebody else. However, science can explain the key features when somebody is falling in love and surprisingly it is not related to heart, as many people thought, but it is related to brain activity.

In 1998, it was quite unusual for a chemical compound became a headline in many media because of this compound. This compound was made by Pfizer and it was intended to be a heart drug but it turned out to help impotent men to have better active sex lives. This compound is called sildenafil which is the active ingredient in Viagra. Sildenafil

In this section, we will see the synthesis of other types heteroaromatics which are indoles and 6-membered rings. Unsurprisingly, those classes of heteroaromatics are common in the organic compounds such as in pharmaceutical and in natural products.  This syntheses will be carried in the same principles as the 5-membered ring heteroaromatics, which is carbonyl chemistry.

Heteroaromatic compounds are commonly found in pharmaceutical, agrochemicals and many known chemicals in the world. In this section, we will see how heteroaromatic compounds can be synthesised and if we examine closely the key reactions in making heteroaromatic compounds are the carbonyls chemistry.
