1.	Which of the following reactions is/are wrong?
Answer» a.`MeCH_(2)I overset(AgNO_(2))(rarr)MeCH_(2)NO_(2) overset(HNO_(2))(rarr)Me-underset(N. OH)underset(\|\|)(C )-NO_(2)overset(overset(ɵ)(OH))(rarr)` Blue colour b.`Me_(2)CHI overset(AgNO_(2))(rarr)Me_(2)CHNO_(2) overset(HNO_(2))(rarr)Me_(2)-underset(N=O)underset(\|)(C )-NO_(2)overset(overset(ɵ)(OH))(rarr)` Blood red colour c.`Me_(3)C-I overset(AgNO_(2))(rarr)Me_(3)C-overset(O)overset(uarr)(N)=Ooverset(HNO_(2))(rarr)No REACTION overset(overset(ɵ)(OH))(rarr)` Colourless solution d.`Me_(3)C-Ioverset(AgNO_(2))(rarr)Me_(3)C-O-N=O overset(HNO_(2))(rarr) "No reaction" overset(overset(ɵ)(OH))(rarr)` Colourless solution Solution :The reaction in `(a), (b)`, and `(d)` are wrong, but the reaction (c ) is CORRECT. In `(a)`, in the end the colour is blood red. In `(b)`, in the end the colour is blue. In `(d), RX` with `AgNO_(2)` gives `RNO_(2)` (nitro alkane) and not `R-O-N=O` (alkyl NITRITE). `Me_(3)C-I overset(AgNO_(2))(rarr) Me_(3)C-NO_(2)`. So the worng reactions are `(a), (b)`, and `(d)`
