Menthyl chloride (2-isopropyl-5-methylcyclohexyl chloride in which Cl is trans to the isopropyl group; all three substituents are equatorial in its stable chair) and neomenthyl chloride (the diastereomer in which Cl is cis to the isopropyl group; in its stable chair Cl is axial while isopropyl and methyl are equatorial) are each treated with $\mathrm{NaOEt}$ in ethanol (E2). Which statement is correct?

1. Aneomenthyl chloride reacts much faster, but mainly gives 3-isopropyl-6-methylcyclohexene
2. Bneomenthyl chloride reacts much faster, mainly giving 1-isopropyl-4-methylcyclohexene; menthyl chloride reacts slowly and gives only 3-isopropyl-6-methylcyclohexene
3. Cboth react at about the same rate and give the same mixture of alkenes
4. Dmenthyl chloride reacts faster because Cl is equatorial, mainly giving 1-isopropyl-4-methylcyclohexene
