JEE Main Chemistry question
A polycyclic substrate bearing a ketone, a nitro group and a pendant vinyl/ester-type group (structure as drawn in the source) →(LiAlH₄ excess, Ether) Product. The number of π-bonds in the major product will be .
Answer: 1
Solution
Excess LiAlH₄ reduces the reducible carbonyl group(s) (ketone/ester) in the substrate fully to alcohol(s), while an isolated, non-conjugated C=C (such as a pendant vinyl group) is
