There are three xylenes. Their melting points are 13 degrees C,
-24 degrees C, and -48 degrees C. Nitration of the isomer with the 13 degree C mp results in only one mononitrated product. The isomer with mp= -24 degree C gives two mononitrated products, and the isomer with mp -48 degrees C gives three mononitrated products. Write the structure for each respective mp isomer and their nitration products.
