WebPhenol (C6H6O or C6H5OH) is a colorless, light-pink, crystalline solid with a sweet, acrid odor. Phenol is a white crystalline solid that is volatile. The molecule comprises a phenyl group (−C6H5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful handling because it can cause chemical burns.
