QUESTION 20 Which observation is NOT consistent with an SN1 mechanism for the conversion alkyl halide? OA Reaction of 2-methylcyclohexanol with H-Br gives 1-bromo-1-methylcyclohexane as the major product. an alcohol into an O B. Methylcyclohexanol is more reactive than 2-methylcyclohexanol towards H-CI. OC Doubling the concentration of chloride ion will double the rate of formation of 2-chloro- 2-methylhexane from 2-methylhexan-2-ol. OD Reaction of R-3-methyl-heptan-3-ol with HI provides a racemic mixture of 3R and 3S 3-iodo- 3-methylheptane.

QUESTION 20
Which observation is NOT consistent with an SN1 mechanism for the conversion of an alcohol into an
alkyl halide?
O A. Reaction of 2-methylcyclohexanol with H-Br gives 1-bromo-1-methylcyclohexane as the major
product.
O B. Methylcyclohexanol is more reactive than 2-methylcyclohexanol towards H-CI.
OC Doubling the concentration of chloride ion will double the rate of formation of 2-chloro-
2-methylhexane from 2-methylhexan-2-ol.
O D. Reaction of R-3-methyl-heptan-3-ol with HI provides a racemic mixture of 3R and 3S 3-iodo-
3-methylheptane.
