Not quite. 2-Bromo-5-chlorophenol is a nice example of something synthetic chemists love: molecular parts that look similar but can behave differently. The molecule has three useful features: An -OH group. A bromine atom. A chlorine atom.
The -OH can be used to attach another molecular fragment through oxygen. The bromine can act as another connection point. With modern cross-coupling chemistry, chemists can replace it with a new piece of molecular architecture. And the chlorine?
