what is meant by activation energy? please reply quickly sir?
It is a minium energy required to convert all reactants into products. Ex: Giving a spark to petrol to burn.We are giving minimum energy in the form of spark, it is a activation energy.

Solid state - If we have to place atoms on alternate face centers how many atoms would be present in fcc arrangement.
we will have 8 atoms at the corners so 8x1/8=1 contributing atoms then for the face centres we have 1/2X6=3 for each alternating face centre 1/2 is contributed.Since the body centred atom is...

What favours the hydride shift in Cannizaros Reaction? We know the hydride is a very poor leaving gropu so why does it leave then?
since we know that hydride shift is RDS in Cannizaro reaction and the carbon cannot exceed its covanlency to 5 also the double bond btw C and O is stronger then hydride it will leave for a...

the group that leaves is basically that group group which doesnt has any role in giving stability
priyanshu gautam 11 months ago
but instead of hydride going out , OH- can leave since it is a much better leaving group than H-
