1.	What are meta directorsexplain with suitable example
Answer» Solution :The group which increasethe electron density at meta position are CALLED as meta directorlet us consider the directive influcence of aldehydic (CHO) group BENZALDEHYDE is resonence hybrid of the following structures In these resonance structures the postivie charge residue is presenton the ring structure it is quite evident that resonance delocalisles the positive charge on the atoms of the ringattack however resonating structures show that electron densityh is more at meta positionas compard to ORTHO and PARA positions hence CHO group is a meta director and a deactivator
