Question

Is the answer for the reaction below correct? I have one mole of terephthaloyl chloride and the starting compound has two nitro groups. It looks too sterically hindered to affect both. Would it just affect one or both?

Is the answer for the reaction below correct? I have one mole of terephthaloyl chloride and the starting compound has two nitro groups. It looks too sterically hindered to affect both. Would it just affect one or both? NO2 1) NaS204, (excess) NaOH, H2O, heat / 2) terephthaloyl chloride (1 mole) NO2 (1 mole)

Explanation / Answer

In the staring compound the two nitro groups are far appart. Hence they are not sterically hindered for any reaction. Theoretically both NH2 group can be affected by terephthaloyl chloride(TCL).

TCL is used for making various copolymers and aramid polymers such as Heracron, kevlar etc.

The answer for the product is correct as only one mole of the starting compound is given.
