Bonding in Co-ordination Compounds
The first theory was called the Werner's theory of co-ordination compounds. 1) Metals possess two types of valencies: a) Primary valency or ionizable valency. It is also referred to oxidation state. b) Secondary valency which a metal atom or cation exercises towards neutral molecules or negative gr..

Points to Remember - Cell is the structural and functional unit of life. The direction in which water flows from one cell to another cell depends on the water potential. Two factors which affect the water potential are the amount of solutes and the external pressure. Due to endosmosis pro..
Turning effect of the force depends upon the perpendicular distance of the axle from the force.
Here the distance d being less, you will have to apply more force to cause the same turning effect...

Alcohols and Phenols are compounds containing -OH as the functional groups. In alcohols, the -OH group is attached to sp 3 hybridised carbon. In phenols, it is attached to sp 2 hybridised carbon of an aromatic ring. In ethers, oxygen atom is attached to two carbons atoms by two separate s..
