Question

m is attached to the first and the fourth vertices. What is the name of the following compound? A line-angle formula shows a ring with six vertices and a circle inscribed. A Cl atom is attached to the first and the fourth vertices.
A. 1,4-dichlorobenzene p-dichlorobenzene
B. phenyldichloride
C. p-dichlorobenzene and 1,4-dichlorobenzene
D. 1,4-dichlorobenzene and phenyldichloride

Answer 1

Answer: Option C. p-dichlorobenzene and 1,4-dichlorobenzene.

Explanation:

A line-angle formula with six vertices and a circle inscribed corresponds to the compound known as benzene.

Further, according to the IUPAC standards for naming benzene derivatives, you must first number the position of the substituent. In this case, the substituents (chloros) are located at the positions 1 and 4; also, for the benzene derivatives when they have 2 substituents and the positions are 1 and 4, this configuration is known as para or p configuration.

Additionally, this compound has 2 substituents (chloros) so you have to indicate this number (di).

Therefore, the correct answer is C. p-dichlorobenzene and 1,4-dichlorobenzene.
