(-OH) – that little symbol, small and neat, Means a hydrogen and oxygen meet! It’s in many things, it’s quite a common sight, From rubbing alcohol to flavors, bold and bright. So "alcohol" isn't just a boozy treat, But chemistry’s building blocks, bittersweet! Do you have any questions? Let’s discuss with glee, Let’s explore this concept for all to see!
