A line-angle formula shows a ring with six vertices and alternating single and double bonds. A CH3 group is attached to the first vertex. An F atom is attached to the third (clockwise) vertex. Spell out the full name of the compound.

1) 3-Ethylanisole

2) 2,3-Dibromobenzoic acid

3) 3-Fluorotoluene

Explanation:

Let us try to look at the structures of each compound one after the other as described in the question.

1) A ring with six vertices and alternating double and single bonds must refer to a benzene ring. A benzene ring having -OCH3 attached to the first vertex is called anisole. If a -CH2CH3 group is now attached at position 3, we now name the compound 3-Ethylanisole.

2) A ring with six vertices and alternating single and double bonds is a benzene ring. If the ring has -COOH attached to the first vertex, we call it benzoic acid. If bromine atoms are attached to the second and third vertices respectively, the compound is now named 2,3-Dibromobenzoic acid.

3) A ring with alternating single and double bonds is a benzene ring. If a -CH3 group is attached to the first vertex, we call the compound toluene. If a fluorine atom is now attached to position 3, the compound can now be named 3-Fluorotoluene
