1.	Assertion (A): In the resonance structure of nitrobenzene, Nitro group accept the bonding electron pair pi-bond from benzene Reason (R ): In the resonance structure of nitrobenzene negative charge is not present on ortho and para position
Answer» STATEMENT (A) and Reason (R ) both are right. Statement (R ) is correct explanation of statement (A) Statement (A) and Reason (R ) both are right, but (R ) is not correct explanation of statement (A) Both Statement (A) and (R ) are wrong Statement (A) is right but statement (R ) is wrong Solution :In nitro group oxygen is attach with nitrogen. ELECTRONEGATIVITY of oxygen `gt` nitrogen so in nitrogroup bonding electron pair of `pi`bond of N=O migrated due to RESONANCE at this time electron pair of alternate `pi`bond of benzene comes out of ring No electron pair on N so it get from aromatic ring No, `e^(-)` pair on N of `-NO_(2)`, so it is not capable to gave `e^(-)` pair therefore it get `e^(-)` pair from aromatic ring. Right: The NEGATIVE charge is not PRESENT at ortho -para position of `-NO_(2)` in nitrobenzene because in resonance structures of nitrobenzene, He ortho -para position are positive charge In above resonance structures of nitrobenzene (II), (III) and (IV) the positive charge present at o-p position but negative charge is not present
