Some Commercially Important Carboxylic Acids
(i) Methanoic acid [Formic acid HCOOH] - It occurs in a variety of biting and stingins plants and insects. It is manufactured by the reaction of carbomonoxide with sodium hydroxide under pressure at 473 K. Sodium methanoate is obtained which is acidified and distilled to give the aci..

Introduction - Sodium belongs to Group I in the periodic table. This group is otherwise known as the alkali metals group. Since the atomic number of sodium is 11, its electronic configuration is 2,8,1. Sodium easily loses the lone electron to attain the stable configuration of neon. Therefore alkal..

Important distinctions between lithium and other family members
Lithium is the hardest of all the alkali metals. The melting and boiling points of lithium are much higher than those of other elements of Group 1. Lithium is less reactive as compared to other metals and it does not get tarnished readily in air. It forms only monoxide, Li 2 O with oxyge..

Aryl diazonium salts constitute intermediates that can be used to synthesis many classes of organic compounds especially aryl halides in the pure state. For e.g., 1,2,3 - Tri bromobenzene is not formed in the pure state by direct bromination of benzene. But it is obtained by a sequence of reactions..

Removal of soluble impurities from sols by the use of semipermeable membrane is known as dialysis. Solutes present in a true solution can pass through a semipermeable membrane such as parchment paper or cellophane. However, sol particles cannot pass through such membranes. When a bag made up of su..

Introduction - Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives. Presently about five million organic compounds are known. Since the synthesis of urea from ammonium thioc..
See what our Users say :
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Very good, Tutor was clear and guided me through the whole algebra problems
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
My son really liked the tutors approach! thanks so much he left the computer feeling postive and confident about his test tomorrow. and that make us (mom and dad) happy!!!!!!
