# Does the position of the functional group on the terminal carbon change the nomenclature?

Consider two alcohols:

$$\rm{CH_3 - CH_2 - OH }$$

and

$$\rm{CH_3 - CHOH - H }$$

In the second alcohol, the hydroxyl radical instead of sticking out from the molecule, is bonded below the terminal carbon, like this $$\rm{H}$$

$$|$$ $$\rm{R- C- H}$$ $$|$$ $$\rm{OH}$$

Now, this doesn't affect the nomenclature (as far as I know), both will be called $\rm{1-ethanol}$. Clearly, these are isomers. But IUPAC nomenclature is supposed to be completely unambiguous. Or did I go wrong somewhere and there actually is a difference in their naming?

PS: Is there any way to produce structural formulas more efficiently in latex on chemistry stackexchange?

• I never tried to draw structures in LaTeX here on Chemistry.SE and to my knowledge, chemfig isn't supported. For me, BKChem with export to png does the job. – Klaus-Dieter Warzecha Jan 29 '14 at 8:16
