Harsha, there is hardly any diff in the mechanisms given by U and biki. U added an extra step that H2O attacks the already attached H2O+ and H3O+ leaves, its the same thing if we say that H+ leaves. We only omit a step.
Biki, I earlier mentioned that U cant predict whether SN1> OR SN2>. These are experimantal observations and U need to learn them wherever they r known. Last H3O+ attacks as the lone pair of O is attracted towards highly positve Hg2+, so it removes Hg2+ and places a H+ instead.
Hope U got it.
The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.
It is during our darkest moments that we must focus to see the light.
