How do we name #(HO)H_2C-CH(CH_3)CH(OH)CH_2CH(CH_3)CH_3# unambiguously?

Answer 1

#2,5-"dimethylhexane"-1,3-"diol"#

#(HO)H_2stackrel1Cstackrel2CH(CH_3)stackrel3CH(OH)CH_2stackrel5CH(CH_3)stackrel6CH_3#

We number FROM the primary alcohol: Clearly, it's a diol derivative, with the longest chain having six carbons.

#2,5-"dimethylhexane"-1,3-"diol"#

I believe this to be clear and accurate, but I may have violated some obscure rule. The molecule has THREE chiral centers as stated. What are their positions?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
