Are cresols phenols?
Cresol is a methyl phenol with meta, ortho, and para isomers. It is used as a disinfectant and antiseptic. Creosote is a mixture of phenols consisting mainly of cresol and guiacol.
What are cresols used for?
Cresols are used to dissolve other chemicals, as disinfectants and deodorizers, and to make other chemicals. Cresols may be formed normally in the body from other compounds. Cresols are found in many foods and in wood and tobacco smoke, crude oil, coal tar, and in chemical mixtures used as wood preservatives.
What kinds of chemical agents are cresols?
Cresols (also hydroxytoluene or cresylic acid) are a group of aromatic organic compounds. They are widely-occurring phenols (sometimes called phenolics) which may be either natural or manufactured. They are also categorized as methylphenols.
Is phenol and cresol the same?
Cresol and phenol are aromatic organic compounds. But, the key difference between cresol and phenol is that cresol has a benzene ring substituted with a hydroxyl group and a methyl group, whereas phenol has a benzene ring substituted with a hydroxyl group.
What is the definition of cresols?
Medical Definition of cresol 1 : any of three poisonous colorless crystalline or liquid isomeric phenols C7H8O that are used as disinfectants, in making phenolic resins and plasticizers, and in organic synthesis — see metacresol, orthocresol, paracresol. 2 : a mixture of cresol isomers. — called also tricresol.
Why are cresols less acidic than phenols?
Phenol is a stronger acid than cresol. This is because in cresol CH3 is an electron-donating group which increases the electron density on the oxygen. This means that there is an increase in the electron density in OH bond making cresol weaker acid than phenol.

Is phenol safe for skin?
Overview. The major hazard of phenol is its ability to penetrate the skin rapidly, causing severe burns. Toxic and even fatal amounts of phenol can be absorbed through relatively small areas of skin. Due to its local anesthetizing properties, skin burns may be painless.
Which is stronger acid than phenol?
Benzoic acid is a stronger acid than phenol.
Why are ortho and para nitrophenols more acidic than phenol?
The nitro-group is an electron-withdrawing group. The presence of this group in the ortho or para position decreases the electron density in the OH bond. As a result, it is easier to lose a proton. Hence, ortho and para nitrophenols are stronger acids than phenol.
