WebPhenol — also known as carbolic acid — is an aromatic organic compound with the formula C 6 H 5 OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C 6 H 5) bonded to a hydroxyl group (-OH). It is mildly acidic, but requires careful handling due to its propensity to cause burns.
