(supported by high dipole of the order of 2 - 2.2 D..

Summary - Electric potential is the condition that determines the flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit of positive charge from infinity to that point. Electrical potential is a scalar quantity. T..

. The overall result is a range of four main layers, D, E, F 1 and F 2 , in ascending order. The last two combine at night to form one single layer. The D layer is the lowest, existing at an average height of 70 km, with an average thickness of 10 km. The degree of its ionisation depends ..

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 protoplasm expands and ..

1) Ionic compounds consist of ions and not molecules. For example, sodium chloride is an electrovalent compound consisting of equal number of sodium and chloride ions. 2) Ionic compounds are hard crystalline solids. The crystal of sodium chloride has a definite shape. There is a strong e..

Summary - 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 ..

Ethane-1,2 diol (Ethylene glycol) - A dihydric alcohol, ethanediol is prepared commercially by acid hydrolysis of epoxy ethane (ethylene oxide..

Benzaldehyde is prepared by side chain chlorination of toluene to benzylidene chloride followed by hydrolysis. Benzaldehyde is a colorless liquid (boiling point 452 K) with the smell of bitter almonds. It is used in perfurmery and dye industry for making dyes like malchi..

Being polar in nature, the acid derivatives have higher boiling points than hydrocarbons of comparable molecular masses. Acid chlorides, anhydrides and esters have nearly the same boiling points as the aldehydes and ketones of comparable molecular masses. The..
