Answer:
i will tell you how i check acid and basic radicals, just see if the radical is forming an acid after combining with H+ ion the given radical then that radical is acid radical and if radical forms base after combining with OH- ion then it is basic radical.
coming to question
formula. basic radical. acid radical
