Isomeric hydrocarbons negative Baeyer's test (Molecular formula C9H12) The total number of isomers from above with four different non-aliphatic substitution sites is -
Answer
2
Solution
No decolourisation of KMnO4 (negative Baeyer's test) no C=C / C C: alkylbenzene (8 isomers).
Distinct ring C–H positions: propyl, isopropyl 3; o-ethyltoluene 4; m-ethyltoluene 4; p-ethyltoluene 2; trimethylbenzenes (1,2,3 / 1,2,4 / 1,3,5) 2 / 3 / 1.
Four different sites:
