Science > Chemistry > Introduction to Organic Chemistry > Classification of Organic Compounds In the last artivle we have studied what is organic chemistry? Why it is termed as chemistry of carbon compounds nowaday? In this article we shall study classification of organic compounds. Depending upon the structure organic compounds are classified into two types. […]
Science > Chemistry > Organic Chemistry > Halogen Derivatives of Alkanes > Physical Properties of Alkyl Halides In the last few articles, we have studied the methods of preparations of alkyl halides. In this article, we shall study the physical properties of alkyl halides. Some physical properties of alkyl halides are as follows: State: Lower […]
Science > Chemistry > Organic Chemistry > Halogen Derivatives of Alkanes > Preparation of Alkyl Halides by Halide Exchange Method In the last three articles, we have studied the methods of preparations of alkyl halides from alkanes, alkenes, alcohols. In this article, we shall study the method of the preparation of alkyl halids by halide […]
Science > Chemistry > Organic Chemistry > Halogen Derivatives of Alkanes > Preparation of Alkyl halides From Alcohols In the last two articles, we have studied the methods of preparation of alkyl halides from alkanes and alkenes. In this article, we shall study the preparation of alkyl halides from alcohols. The Action of HX on […]
Science > Chemistry > Organic Chemistry > Halogen Derivatives of Alkanes > Preparation of Alkyl halides From Alkenes In the last article, we have studied the preparation of alkyl halides from alkanes. In this article, we shall study the preparation of alkyl halides from alkenes (olefins). The Action of HX on Alkenes: It is an […]
Science > Chemistry > Organic Chemistry > Halogen Derivatives of Alkanes > Preparation of Alkyl Halides From Alkanes In this article, we shall study methods of preparation of alkyl halides from alkanes. Alkyl halides can be prepared from alkanes by their halogenation. General Reaction: R – H + X– X → R – X + […]
Science > Chemistry > Biomolecules > Proteins and Their Classification The name protein (proteios Greek = pre-eminent or first) was first suggested, in 1838, by a Swedish chemist Berzelius to a Dutch chemist Mulder, who referred it to the complex organic nitrogenous substances found in the cells of the living beings. They are naturally occurring nitrogenous polymers of different alpha-amino […]
Science > Chemistry > Introduction to Organic Chemistry > Chemistry of Carbon Compounds Organic chemistry is a branch of chemistry, which studies carbon compounds. Organic substances are substances derived from organisms like plants and animals. In the olden days it was assumed that these substances cannot be prepared in laboratories. Berzelius assumed that some vital […]
Science > Chemistry > Biomolecules > Disaccharides and Polysaccharides In the last article, we have studied monosaccharides. In this article, we shall study disaccharides and polysaccharides. Disaccharides: Di-saccharides on hydrolysis give two molecules of monosaccharide. They on hydrolysis with dilute acids or enzymes yield two molecules of either the same or different monosaccharides. e.g. Cane sugar (Sucrose) […]
