positive iodoform test

Formation of yellow precipitate of iodoform is used as a test for certain aldehydes and ketones that have methyl group bonded to carbonyl group CH 3 CO- or compounds that can form this group on oxidation e.g. This test is performed by heating the substance with aque..

It is a yellow colored crystalline solid with melting point 392 K. It has a characteristic unpleasant odor. It is insoluble in water but readily dissolves in ethyl alcohol and ether. Due to liberation of free iodine it has an antiseptic action..

Kinetic energy of the body = 0 (Since the body is at rest, i.e., v = 0) Potential energy of the body = mgh. Therefore the total mechanical energy = mgh + 0 = ..

If the velocity of an object increases then the object is said to be moving with positive acceleration...

Haloalkanes with three or more carbon atoms exhibit position isomerism in which the isomers differ in the position of halogen atom. For example, C 3 H 7 I has two position isomers:..

A vector which gives the position of a point with reference to the origin of the coordinate system is called position vector. The figure above illustrates the position vector of a particle moving in the X-Y plane. Let the particle be at P at any instant of t..

This isomerism arises due to the difference in the position of the same functional group or the same substituent while the arrangement of carbon atoms remains same. For example, Chloropropane (C 3 H 7 Cl) can have two positional isomers given below. Butene (C 4 H..

It is a positive inter specific interaction in which both the partners are mutually benefitted and increase the chance of their survival. However, the interaction is not obligatory for their survival as both can live without this interactio..

The position of hydrogen was not correctly defined. It was placed in Group I although its properties resembled both the Group I elements (the alkali metals) and the group VII elements (the halogens..
