you have to do it atom by atom. So compare the the atomic number of Cl to the atomic number of C in the carbon chain. Cl has a higher atomic number. Therefore, it has as higher priority, and it is trans (E)

Yes. The main chain must always include the functional group since functional groups have the highest priority in naming.
Why is the substituent given priority in regards to naming? In other words, why wouldn't it be 3-(3-chlorocycloheptnyl)-2-methylpropan-1-ol? I thought that the functional group always receives the lowest number.
