# What a Compound! (Comes Back!)

Chemistry Level 5

Which of the following statements related to $$\text {Cyclohexane}$$ are correct ?

1 - $$Half$$ $$Chair$$ conformer of cyclohexane is most stable.

2 - $$Boat$$ $$form$$ conformer of cyclohexane has angle strain .

3 - $$Half$$ $$Chair$$ conformer of cyclohexane is free from angle strain.

4 - Cyclohexane has the lowest heat of combustion compared to other cycloalkanes ( eg: cyclopropane, cyclobutane etc.).

5 - The stable form of cis-1,2-dimethylcyclohexane(Chair form) is (1e, 2e ). $$[e-equatorial$$ , $$a-axial position]$$.

6 - The stable form of $$cis-2-methylcyclohexanol$$(Chair form) is [1a (Me) , 2e (OH)].

7 - The stable form of $$cyclohexane-1,4-diol$$ is boat form.

10 - $$1,4-dimethylcyclohexane$$ is optically active.

Enter your answer as the product of the respective option numbers of correct response.

$$\text {Clarification}$$ : If you think statements 2,3 and 5 are true, enter your answer as $$2 \times 3 \times 5 = 30.$$
