halogens oxidising agents

Oxidising Power of Halogens - Halogens have high electron affinity values and therefore they have strong tendency to take up the electro..

The substance that oxidizes the other substance is called the oxidizing agent..

Chemical Properties of Sulphur - With Oxidising Agents - When sulphur is mixed with potassium nitrate, potassium chlorate etc., it forms an explosive mixture. When struck or heated or ignited, the mixture explodes e.g. gun powde..

The reaction with fluorine is violent and cannot be controlled. Therefore, fluoroarene cannot be prepared by direct fluorination of aromatic hydrocarbon. Bromo compounds can be prepared in a similar way by reacting with Br 2 in the presence of FeBr 3 . Iodoarenes are also difficult to prepare by di..

Summary - Chlorine belongs to group VII A. Members of this group are called halogens which means 'salt producers'. Chlorine is a greenish yellow gas. Chlorine has seven electrons in its outer most shell and so has a valency of 1. Like other halogens chlorine is a strong oxi..

Some characteristics of inter halogen compounds are: (i) They are covalent compounds. (ii) They are more reactive than the constituent halogens. It is because A-X bond is relatively weaker than X-X bond. (iii) They are very good oxidising agents. (iv) Their m..

. The presence of substitutents in the aromatic ring effects the acid strength of phenols. Election withdrawing groups in ortho and para positions increase acid strength and electron - releasing groups decrease it. Alcohols undergo nucleophilic substitution with hydrogen halides to yield alkyl hali..

Aldehydes and ketones are generally prepared by oxidation of primary and secondary alcohols respectively. Common oxidising agents are KMnO 4 , K 2 Cr 2 O 7 and CrO 3 . Strong oxidising agents oxidise the aldehyde produced by the oxidation of ..
