This chapter contains oxygen compounds in which oxygen is bonded to a carbon atom through a double bond. The functional unit >C = O, present in these compounds is called carbonyl group. We limit our study now to compounds having an acyl group (R - C = O) is bo..

Introduction - This chapter contains oxygen compounds in which oxygen is bonded to a carbon atom through a double bond. The functional unit >C = O, present in these compounds is called carbonyl group. We limit our study now to compounds having an acyl group (R - C =..

The scientific methods of collection of data, its classification and application to commerce and everyday life is called statistics. A list of some important terms as follows: (i) ungrouped data (ii) tabulation of data (iii) range (iv) frequency (v) frequency distribution (vi) tally (vii) inc..

A discrete variable can assume only integral values which can be counted. Number of pupils in a school, persons working in a factory are examples of discrete variables. A list of some important terms is given below. (i) ungrouped data (ii) tabulation of data (iii) range (iv) frequency (v) frequenc..

It is a vertical stroke put to represent a particular score. After 4 vertical strokes the fifth stroke is drawn across them to make a bunch of five. This makes the totalling easier. If the number of scores is large, then the range is divided into a number of classes. The tally score is obtained fo..

Catenation is the tendency of an atom to form bonds with identical atoms. In this group only sulphur has a strong tendency for catenation. Oxygen also shows this tendency to a limited extent. Thus the polyoxides and polysulphides of the following types are known: H 2 O 2 , H - ..

. This group of pesticides can kill all insects / animals including all beneficial predators / parasites of pests. The use of ecofriendly pesticides has not offered solutions to many pests (e.g., coconut mites). Where is the solution for pernicious problems? In many countries (including I..

Molecular hydrides are soft. They are generally, volatile in nature and have low melting and boiling points. They have low electrical conductivity. The electronegativity difference between hydrogen and the atom bonded to it, determines the properties of covalent hydrides. When moving fro..

Excretion and Osmoregulation in Amoeba - Amoeba is a protozoan which forms the simplest of all groups in the animal kingdom. Inspite of being unicellular it is physiologically balanced and performs all the essential processes of an animal. Carbon dioxide, urea, uric acid and mineral salts..
