Question

True/False Indicate whether the statement is (A) true or (B) false. In the most stable conformation of a cyclohexane, it is preferable to have as many substituents in the axial position as possible. 2. 3. Syl reactions may involve a carbocation rearrangement. Tertiary alkyl halides are more likely to participate in an Sy2 reaction. 4. Cis-1,3-dimethyleyclohexane and trans-1,3-cyclohexane are enantiomers. 5. 6. An Sy2 reaction results in inversion of the relative configuration. The rate of an SNl reaction can be increased by increasing the concentration of the nucleophile. 7. 8. Syl reactions occur in one step. 9. A carbocation rearrangement will occur in the reaction of 2-bromo-3-methylbutane with methanol.
