Q. Explain about Preparation of diborane? Diborane can be prepared in almost quantitative yields by the reduction of boron Tricloride etherate (BF 3 , 0Et 2 ) with lithium alum
All electrons on the 4p sub-shell must be characterized by the quantum number(s): (1) n=4, m= 0, s= ± 1/2 (2) l=1 (3) l=0, s= ± 1/2
COMPOUNDS A AND B CONTAIN COPPER AND SULPHUR.EACH CONTAINS 20% AND 33.33% EACH BY MASS OF SULPHUR RESPECTIVELY.FIND THE RATIO OF THE ELEMENTS USING THE THIRD LAW OF CHEMICAL COMBIN
Number of electrons in -CONH 2 is: (1) 22 (2) 24 (3) 20 (4)28 Ans:24
The electron pair which forms a bond between two similar non-metallic atoms will be: (1) Dissimilar shared between the two (2) By complete transfer from one atom to other
When a strip of metal (M) is brought in contact with the solution containing its own ions (Mn+), then either of the following three possible processes can take place: The meta
