6. Which of the following compounds is phenol?

a.		c.
b.		d.

7. Which of the following compounds is a hydrocarbon?

a.	aniline	c.	phenol
b.	nitrobenzene	d.	toluene

8. Which of the following correctly describes the two aromatic ring substituents in the xylenes?

a.	They are both hydroxyl groups.
b.	They are both methyl groups.
c.	One is a methyl and one is an hydroxyl.
d.	One is a methyl and one is an ethyl.

9. What is the correct IUPAC name of the following compound?

a.	1-ethyl-4-bromobenzene	c.	1-bromo-4-ethylbenzene
b.	4-ethyl-1-bromobenzene	d.	4-bromo-1-ethylbenzene

Expert Solution

6. There are no options found.

7. Option D, toluene is hydrocarbon. Because, hydrocarbon means compound containing only carbon and hydrogen. Toluene means CH3 group upon benzene ring, it contains only C and H.

All other option contains heteroelement other than C and H. i.e., Aniline contains N, Nitrobenzene contain N and O, Phenol contains O along with C and H.

8. Option b is correct. Because, xylene is a compound in which there are 2 CH3 groups on benzene ring. It can be ortho or para or meta each other.

9. Option C is the answer. Because,, while writing it should follow alphabetic order. So, B(bromo) come first than E(ethyl). Then Br carbon should be the 1st carbon not 4th. according to priority rule.
