Question

Consider the following reaction sequence 'R' can not be in given compounds is x then find x ?

TestHub · Accepted Answer

Conc. H₂SO₄ + heat → elimination → alkene formed

KMnO₄/OH⁻ → syn-dihydroxylation (cis-diol)

Br₂/H₂O or NaCl → halohydrin formation (anti addition)

Anti addition gives Br and OH in opposite directions

Check given structures: only those satisfying anti addition + correct orientation are possible

One structure violates stereochemistry (wrong orientation of groups)

Answer: 5 correct structures (one is not possible)
