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