Q. What is Diborane?
The chemistry of diborane has aroused considerable interest because of its usefulness in many synthetic reactions and also because the elucidation of its structure helped to clarify the basic concepts about the structure of electron deficient compounds.
What is the maximum number of electrons which can be accommodated in an atom in which the highest principal quantum number value is 4: (1) 10 (2) 18 (3) 32
what are the chemical properties of colloids
lithium and beryllium markedly differ from other members of their respective groups.
Write and balance the equation for the burning of an unknown hydrocarbon, C4H9 in air.
Calculating equilibrium constant
We are asked to design a qualitative analysis scheme that can be used to determine which cations are present in a solution containing only four of the following cations: Pb2+, Ag+,
Question: Steam initially in a vapor/liquid mixture with 80 percent liquid at 250C, expands isothermally and reversibly to a final state at 20 bar. Using the steam tables: a
An open test tube at 293 K is filled at the bottom with 24.2 cm of Hg, and 11.2 cm of water is placed above the Hg. Calculate the pressure at the bottom of the test tube if the at
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
