How to Name Cycloalkanes

Draw bond-line formulas and give lUPAC substitutive names for all of the isomerie alcohols with the formulas (a) C4H10O and (b) C5H12O. 

Simple alcohols are often called by common functional class names that are also approved by the lUPAC. We have seen several examples already (Section 2.6). In addition to methyl alcohol, ethyl alcohol, and isopropyl alcohol, there are several others, including the following  

Alcohols containing two hydroxyl groups are commonly called glycols. In the lUPAC substitutive system they are named as diols  

Cycloalkanes with only one ring are named by attaching the prefix cyclo- to the names of the alkanes possessing the same number of carbon atoms. For example, 

Naming substituted cycloalkanes is straightforward We name them as alky Icy cloalkanes, halocycloalkanes, alky Icy cloalkanols, and so on. If only one substituent is present, it is not necessary to designate its position. When two substituents are present, we number the ring beginning with the substituent first in the alphabet and number in the direction that gives the next substituent the lower number possible. When three or more substituents are present, we begin at the substituent that leads to the lowest set of locants
