Select cresol out of the following benzene derivatives?
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Cresol is a derivative of benzene that has a methyl group CH3 and a phenol group OH attached to the benzene ring.Ortho-Cresol, also called 2-methylphenol, or 2-hydroxytoluene, is an organic compound with the formula CH₃C₆H₄. It is a colourless solid that is widely used intermediate in the production of other chemicals. It is a derivative of phenol and is an isomer of p-cresol and m-cresolMetacresol (m-cresol or 3-methyl phenol) is a colorless, yellowish liquid. It is used as a bactericide for control of crown gall and olive knots on certain fruit and nut trees and ornamentals and the genetic/physiological disorder burr knot on apples.Para-Cresol, also 4-methylphenol, is an organic compound with the formula CH₃C₆H₄. It is a colorless solid that is widely used intermediate in the production of other chemicals. It is a derivative of phenol and is an isomer of o-cresol and m-cresol.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
