what is the molarity of the solution prepared by dissolving 75.5 g of pure KOH in 540 ml of solution
Which is more reactive towards nucleophilic substitution aryl halide or vinyl halides
are halides are halogens more soluble? why?
The entropy due to the rotational motion of the molecules of a gas can be calculated. Linear molecules: as was pointed out, any rotating molecule has a set of allowed rotational energies. For a linear molecule the
