Answer:

See explanation

Explanation:

When we have to write an organic molecule, we have to remember the <u>IUPAC rules.</u> In this case, we have: "2,5-dimethylfuran". We can divide the name into two parts:

<u>a) "2,5-dimethyl"</u>

<u>b) "Furan"</u>

For part a) we have the indications of the <u>"subgroups</u>" bonded to the main structure, in this case, we have 2 <u>methyl groups</u> (CH_3) bonded to carbons 2 and 5.

For part b) we have the main, structure. In this case furan, this compound is a <u>cyclic structure</u> of 5 members in which we have in the middle of the molecule an oxygen atom and  2 double bonds (see figure 1).

Finally, when we add the methyl groups to the furan we will get the 2,5-dimethylfuran. (see figure 2).

I hope it helps!
