Question

What is the structure of Cyclohexyl methanol?

• A. \(C_{6}H_{5}-CH_{2}OH\) (Benzyl alcohol)
• B. \(C_{6}H_{11}-CH_{2}OH\) (Cyclohexyl methanol)
• C. \(C_{6}H_{11}-OH\) (Cyclohexanol)
• D. \(CH_{3}-C_{6}H_{10}-OH\) (Methyl cyclohexanol)

Hint:

Do not confuse these compounds: \[ \boxed{ \begin{aligned} C_6H_5CH_2OH &\rightarrow \text{Benzyl alcohol}\\ C_6H_{11}CH_2OH &\rightarrow \text{Cyclohexyl methanol}\\ C_6H_{11}OH &\rightarrow \text{Cyclohexanol} \end{aligned} } \] The suffix "methanol" indicates that the \(-CH_2OH\) group lies outside the ring.

Answer 1

The Correct Option is B

Cyclohexyl methanol consists of a cyclohexane ring with a $-CH_2OH$ (hydroxymethyl) substituent attached to one ring carbon. The carbon bearing the $-OH$ group ($-CH_2-$) is bonded to only one other carbon, making this compound a primary alcohol.
