Organic Chemistry Questions! Any help is appreciated!?

1. Draw a mechanistic picture for the E1 elimination of the compound undergoing faster elimination in question 10. Show all possible products. 

2. Which isomer is likely to have a faster elimination reaction, trans-1-bromo--3-tert-butyl cyclohexane, or cis-1-bromo--3-tert-butyl cyclohexane? Draw each molecule in its more stable chair conformation (with the tert-butyl group equatorial) and explain your answer. 

3. Predict whether the following reactions are likely to be SN1 or SN2: 3-Buten-2-ol + HCl  3-chloro-1-butene 3-Bromo-2-methyl-1-propene + OH-  2-methyl-2-propen-1-ol 2-Bromo-2,2-dimethylpentane + H2O  2,2-dimethyl-2-pentanol 

9. What products would you expect from elimination reactions of the following alkyl halides? In the case of mixtures, indicate the major product. (a) 3-Bromo-2-methylhexane (b) 3-Chloro-2,4-dimethylpentane (c) 1-bromo-1-methylcyclohexane
