Lecture Notes on the Structure and Nomenclature of Alkenes
 
  1. Identify the longest continuous chain that contains the C=C.
  2. Use the ending -ene to indicate the presence of the C=C.
  3. Number the chain so that the first carbon of the C=C reached has the lowest possible number.
  4. Name and number substituents in the same fashion as in alkanes.
The alkene functional group takes precedence over alkyl and halide functional groups.

The alcohol functional group takes precedence over the alkene functional group.
To number the cycloalkene, one carbon of the C=C is given the number 1 and the other carbon of the C=C is given the number 2. Numbering is done to give the alkyl groups the lowest possible numbers.
 
 
 
 
 
 
 
The designation cis and trans are not unambiguous here.
