What is the structure of o-cresol?
ortho-Cresol, also called 2-methylphenol, or 2-hydroxytoluene, is an organic compound with the formula CH3C6H4(OH). 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-cresol.
What is the use of o-cresol?
It is mostly used as an intermediate for the production of pesticides, epoxy resins, dyes and pharmaceuticals, but also as a component of disinfectants and cleaning agents. o-Cresol is “readily biodegradable” and has a low bio- or geoaccumulation potential.
What is Colour of o-cresol in alcoholic solution?
O-cresol appears as colorless or yellow to brown-yellow or pinkish colored liquid with a phenol-like odor.

Which is more acidic phenol or o-cresol?
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 cresol an alcohol?
o-Cresol is aromatic and directly attached with benzene ring. o-Cresol is vinylic and benzylic alcohol is allylic. Allylic benzyl alcohol would give iodoform test while o-cresol will not. Therefore, they are functional isomers.
Is o-cresol an acid or base?
The o-cresol is the least acidic as the electron-donating group is very near to the anion which will be formed after donating hydrogen which destabilizes it.
Which is more acidic o-cresol and p-cresol?
However, due to the stronger +I effect at ortho position than that at para position(+I effect decreases with distance), ortho-cresol is a weaker acid than para cresol. Thus, the order od acidic strength in increasing order is: ortho-cresol < para-cresol < meta-cresol < phenol.
How do you make o-cresol?
0-cresol and 2,6-xylenol are prepared by flowing a gaseous stream of methanol and phenol in a molar ratio of phenol to methanol of from 1:1 to 1:9 through a fluidized bed of alumina particles at a temperature of from 200° to 400° C., said alumina being in the eta, gamma or chi crystallographic form, having a surface …
Which one is more acidic o-cresol?
O-nitrophenol is more acidic than O-cresol.

Which is more acidic o-cresol or phenol?
Which is more acidic o-cresol or m-cresol?
The o-cresol is the least acidic as the electron-donating group is very near to the anion which will be formed after donating hydrogen which destabilizes it. Therefore, the acidity order will be m-cresol > p-cresol > o-cresol that shows option C as the correct choice.
Which of the following is most acidic a phenol B O-cresol C p-cresol D M cresol?
Phenol is a stronger acid than cresol.
Which is more acidic phenol or Ortho nitrophenol O-cresol?
Answer : o-nitrophenol , Ortho-nitrophenol is more acidic because of the presence of an electron-withdrawing group (–NO2) at an ortho position with respect to the –OH group, which enhances the acidic strength of the compound by stabilizing the phenoxide ion and therefore, o-nitrophenol can easily release a proton.
