    (CH3)2C=C(CH3)OH

    I posted it in another forum by accident. Hydroxyl group, methyl group, double carbon bond.

    My chemistry is a bit rusty but wouldn't that be 2-propylethanol ?

    OK, very rusty... I don't know.

    I guess it is a prenol (3-methyl-2-buthenol):

    also no, because the question contains double carbon bonds (alkene).

    I forgot the name but I'll draw it.

    I guess no, it should contain an alkene name (because of the double bond).
    Like butanol --> butenol.

    That one would be:


    --------OH
    --------|
    CH3--CH--CH3

    2-propanol (2 propylethanol)

    and that would be:


    --------OH
    --------|
    CH3--C--CH3
    --------|
    --------CH3

    See the problem is that I forgot how the double bond is made clear in the name.

    Shouldn't there be a double bond in there ?

    3-methyl-2-buthenol. Under IUPAC nomenclature, when there is both double
    bonds and hydroxyl, the numbering is started from C that closer to the hydroxyl.
    (I'm not so sure, though).

    Btw, not butanol, but buthenol. The double bond shows it isn't an alkane but alkene.

    I have to draw it first to give the numbers and the position of alkyl

    Ok, yeah. Didn't know for sure.

    So 3-methyl-2-buthenol it is. (not butanol ? Are you sure ?)
