Question

Isomeric hydrocarbons \( \rightarrow \) negative Baeyer's test (Molecular formula \( \text{C}_9\text{H}_{12} \)). The total number of isomers from above with four different non-aliphatic substitution sites is -

Hint:

When dealing with isomeric hydrocarbons, focus on the positions of non-aliphatic groups and the potential for different bonding arrangements.

Answer 1

Correct Answer: 2

The molecular formula \( \text{C}_9\text{H}_{12} \) indicates that the compound is likely to have several isomers due to the possibility of different types of substitutions. For this molecular formula, there can be isomers with various positions for non-aliphatic substitution.
There are 3 distinct isomers of \( \text{C}_9\text{H}_{12} \) with four different non-aliphatic substitution sites as shown in the answer. These include positional isomers and functional group isomers.
Thus, the correct number of isomers is \( \boxed{(2)} \).
