The major product of the following reaction is
[figure: benzene ring with on the top vertex and on the adjacent upper-left vertex]
The figure, in words
Stem: benzene ring with OCH3 and NO2 on adjacent carbons, reagents (i) Na/liq.NH3 (ii) CH3CH2OH. Options are drawn non-aromatic six-membered ring structures; double-bond positions described approximately from the drawing.- (1)[figure: six-membered ring; one ring carbon bears H and (sp3), the adjacent ring carbon bears ; two C=C double bonds drawn in the ring (one on the -bearing carbon, one along the lower-left edge)]Official answer
- (2)[figure: six-membered ring; one ring carbon bears H and (sp3), the adjacent ring carbon bears ; two C=C double bonds drawn in the ring (one on the -bearing carbon, one along the lower-left edge)]
- (3)[figure: six-membered ring; top ring carbon bears OH, the adjacent left ring carbon bears ; C=C double bond between these two carbons and a second C=C along the lower-right edge]
- (4)[figure: six-membered ring; top ring carbon bears and H (sp3), the adjacent left ring carbon bears ; two C=C double bonds drawn along the left and right sides of the ring]
