Answer 1

NaoH The mechanism is LoH Scanned with CamScanner

As the intermediate carbanion is more stabilized the more the reactont is reactive. el 1 CKEN Cena No , No, : No has -R and I effect so, when No2 Present in ortho-para position is ctorilizes the carbonion so @ ; ® are reactive CLR effect of No2). But Noz in meta position has only -I effet co@.@ more reactive than one a carbonion is more d has two-No2 groups so Carbon I Stabilized than b. So, b is least reactive CS scothaith and wer is 6 Camſcanner
