Community shelf Community shelf -> What is the difference between a Lewis acid (Electrophile) and a base(nucleophile)? -> Go to message
This Post 0 points    (0 Olaaa!! Perrrfect answer.   in 0 votes )   [?]

The essential difference is that the acidity/basicity is a thermodynamical property, measured with the equilibrium constant, while the electrophilicity/nucleophilicity is a cinetic property, measured with the kinetic constant. So, a strong lewis acid, for ex., can react slowly with a lewis base and so be a weak electrophile; or a strong electrophile, which reacts fast with a nucleophile, can have a low equilibrium constant and so be a weak lewis acid. Usually a strong lewis acid/base is also a strong electrophile/nucleophile, but it's not always so, for the reason I've written.

 Actually the correspondence from BRILLIANT TUTORIALS would be the best...they emphasize on concepts and they give you ample amount of answers at the end of each chapter and you get the solutions in the next edition...

This Post 0 points    (0 Olaaa!! Perrrfect answer.   in 0 votes )   [?]

No. A reaction is spontanoeus only if free energy change,i.e., ^Gis negative. Physisorption is an example where as the reation proceeds, it becomes endothermic yet it is spontaneous...

What are the negative aspects of dropping a year? Is that a question? Is there anything postive about that at all? Except that you won't have to buy new books for a year, I don't see anything postive but then you will be paying more than that as fees...
