    no , shweta. -I of NO2 is greater than CN. because EN of N is greater than C Here distance is dominant over strength so III>II>IV>I. in case of II and III, less distance so more -I and more stability of Carbanion. now we will check -I strength because distance is same. and we know -I NO2> CN so III>II.
