Anhydrides are on the whole less reactive than acyl chloride..

This reaction is used for introducing an alkyl (R-) or acyl (RCO-) group into the benzene ring. Benzene, in the presence of anhydrous aluminium chloride (AlCl 3 ), reacts with substances such as haloalkane (RX), alcohol (ROH) and acid chlorides (RCOCl) etc., to give the corresponding derivative of..

As the earth cooled further, the primitive inorganic molecules interacted and combined with one another to form simple organic compounds. Simple sugars, fatty acids, glycerol, amino acids and nitrogen bases (purines and pyrimidines) were probably the simple organic compounds that resulted..

Chemical evolution resulted in the formation of life on earth about 3.8 billion years ago. The primitive cells that resulted from this process gradually gave rise to primitive forms of organisms such as bacteria, algae, fungi and protozoan. These organisms in turn, gave ri..

Solar cells convert light energy of the sun into electrical energy. They provide almost the complete power for required space crafts and artificial satellit..

According to this theory, the reducing atmosphere of primitive earth helped in the formation of simple inorganic compounds followed by simple organic compounds. Then complex organic compounds and subsequently their interaction leading to the formation of self duplicating nucleic aci..
