match each structure to its name.\n1. ortho - difluorobenzene\n2. meta - difluorobenzene\n3. para…

Brief Explanations:

In organic - chemistry, the prefixes ortho - (o -), meta - (m -), and para - (p -) are used to describe the relative positions of substituents on a benzene ring. Ortho means the substituents are on adjacent carbon atoms (1,2 - position), meta means they are separated by one carbon atom (1,3 - position), and para means they are on opposite carbon atoms (1,4 - position). For the first structure, the two fluorine atoms are in the 1,3 - position, so it is meta - difluorobenzene. For the second structure, the two fluorine atoms are in the 1,4 - position, so it is para - difluorobenzene. For the third structure, the two fluorine atoms are in the 1,2 - position, so it is ortho - difluorobenzene.

Answer:

1. 2. meta - difluorobenzene
2. 3. para - difluorobenzene
3. 1. ortho - difluorobenzene
