Question

Draw the structures of phenetole and o-Cresol.

Answer 1

Hint: Phenetole is ethyl phenyl ether; that is, an ethyl group and a phenyl group on either sides of an ether group. o-Cresol is also known as $2-$methyl phenol, and consists of a methyl group on the ortho position of phenol.

Complete step by step answer:
First let us try to draw the structure of phenetole. This compound is an ether, and thus, consists of an oxygen group sandwiched in between two other groups. In phenetole, the first such group is a phenyl group, and the next group is an ethyl group. Thus, it is also known as ethyl phenyl ether. Its structure is given below:

The IUPAC name of phenetole is given as ethoxybenzene.
Now let us look at the second compound given and try to draw its structure.
o-cresol is an isomer of cresol, and has the IUPAC name $2-$methyl phenol. Thus, it is a phenol derivative and its structure constitutes of a methyl group at the ortho position of phenol. We can draw its structure as follows:

Additional information:
Phenetole is a colourless oily liquid with a distinctive odour. It is mainly used as a research chemical and as an intermediate in the perfume industry. O-cresol is a colourless solid that is extracted from coal tar. It mainly acts as a starting material in the production of other compounds.

Note: Structure of compounds are drawn according to the IUPAC name, which specifies the preference of placing functional groups in the compound.
Note that the other isomers of cresol are m-cresol and p-cresol. Isomers are compounds with the same molecular formula but different structural formula.
