JEE Main 27 August 2021, Shift 2, Chemistry Q47
Question 47 of 90 in this shift, Chemistry question 17 of 30, Section A.
The correct structures of A and B formed in the following reactions are :
[reaction drawn: a benzene ring with OH at the top and at the bottom, arrow labelled , giving A; then arrow with a drawn structure of two C=O groups joined through a single O, each C=O carbon also bearing a plain line labelled 1.0 eq. giving B (Major Product)]
The figure, in words
Stem: p-substituted benzene ring (OH top, NO2 bottom) -> A (H2/Pd, C2H5OH) -> B with a drawn two-C=O reagent, 1.0 eq. Options give structures for A and B.- (1)A: [benzene ring with OH at the top and at the bottom]; B: [benzene ring with OH at the top, a group on the ring carbon adjacent to the OH carbon (upper right), and at the bottom]
- (2)A: [benzene ring with at the top and at the bottom]; B: [benzene ring with at the top and at the bottom]
- (3)A: [benzene ring with OH at the top and at the bottom]; B: [benzene ring with OH at the top and at the bottom]Official answer
- (4)A: [benzene ring with OH at the top and at the bottom]; B: [benzene ring with at the top and at the bottom]
