The common name tert-pentyl alcohol refers to the molecule with the structure CH3CH2C(CH3)2OH. The correct IUPAC name for this molecule is 2-methyl-2-butanol, which corresponds to choice C. Choice A, 2,2-dimethyl-1-propanol, refers to a different molecule with the structure (CH3)2CHOHCH3. Choice B, 2-ethyl-2-propanol, refers to the molecule CH3CH2CHOHCH(CH3)2, which is also different from tert-pentyl alcohol. Choice D, 3-methyl-1-butanol, refers to the molecule CH3CH2CH(CH3)CH2OH, which has a linear chain and is also different from tert-pentyl alcohol. Choice E, methyl tert-butanol, refers to a molecule with the structure (CH3)3COH, which is different from tert-pentyl alcohol because it has a tert-butyl group (-C(CH3)3) instead of a pentyl group (-C4H9).
