Homework Answers
Lewis acid is the species which has tendency to accept electrons. Lewis acid either posses positive charge or partial positive charge or vacant orbital.
Lewis acid should have deficiency of Electrons.
O2- has 2 Electrons extra and its octate is also complete (8 Electron) so it can't work as lewis acid.
