Explain your answers, showing the degree of substitution of each double bond in the products.

1. Predict the elimination products of the following reactions. When two alkenes are possible, predict which one will be the major product. Explain your answers, showing the degree of substitution of each double bond in the products.

2. Which of these reactions are likely to produce both elimination and substitution products?

(a) 2-bromopentane + NaOCH₃

(b) 3-bromo-3-methylpentane + NaOMe (Me = methyl, CH₃)

(c) 2-bromo-3-ethylpentane + NaOH

(d) cis-1-bromo-2-methylcyclohexane + NaOEt (Et = ethyl, CH₂CH₃)
