Question

my question is abot Sn2 reactions. what are they and how are they formed.. illubriate your answer with full details" e.g." what atoms are more electroegative than others and why they attrack other atoms electrons?

Answer 1

Electronegativity increases to the left of the period and decreases down a group. So O<N<F. O>S and N>P. The more electronegative an atom, the greater the pull on their electrons and on the other electrons in a shared covalent bond. So the electron pair in abond, sort of shifts towards the electronegative atom.
