chemical properties of materials

. Both those dipeptides have 3 free functional groups which further react with relevant groups of other amino acids forming tri, tetra, penta peptides and so on. Both -CO and -NH groups of peptide bonds are polar. They are involved in hydrogen bond formation. In a protein the amino acids are held t..

Michael Faraday discovered that a specimen of bismuth was repelled by a strong magnet. Diamagnetism occurs in all materials. These materials are those in which individual atoms do not possess any net magnetic momen..

Chemical Properties - In organic nitrile, nitrogen of the nitrile group can react with the electrophilic reagent and the carbon of the nitrile group can react with a nucleophilic reagent. The unsaturated cyano group can also be reduc..

Ethanol, being a monohydric alcohol exhibits the properties particular of that series. Monohydric alcohols can be considered as derivatives of alkanes obtained by replacing one hydrogen atom by a hydroxyl group. Similarly, they can be considered as derivatives of water obtained by replac..

Differences in chemical properties Metals have 1, 2 or 3 electrons in the outermost shell Non-metals have 4 to 8 electrons in the outermost shell Loses valence electrons and forms cations Gain or share valence electrons and form anions Electropositive Electrone..

On hydration, quick lime forms slaked lime or lime water. When water is added to lime it becomes hot and cracks to form a white powder. This is called slaking of lime. Calcium oxide is a basic oxide. It can react with acids to give calcium salts. With acidic oxides like silicon dioxide an..
