Predicting Solubility of Alcohols

we count the number of alkyl groups attached directly to the a carbon. In this case, there are two alkyl groups  

PROBLEMS Identify whether each of the following alcohols is primary, secondary, or tertiary  

An alcohol, by definition, will contain an OH group in its structure. Therefore, we expect hydrogen bonding to occur  

You might learn about the structure of DNA at the end of your organic chemistry course. For right now, we will be focused on problems that deal primarily with small molecules and therefore, for our purposes, we should think of H-bonding as an interaction a type of intermolecular force. 

In the case of methanol, the hydrophobic end of the molecule is fairly small. This is true even of ethanol and propanol. But an interesting thing happens when we look at 1-bntanol. The hydrophobic end of the molecnle is now large enough to prevent miscibility
