- (b) Compound L, C4H9BR undergoes the substitution reaction with ammonia, NH3 to form butan-2-amine. The reaction of compound L with magnesium, Mg in ether produced compound M. The hydrolysis reaction of compound L with water, H2O produced compound N. Compound P is produced when compound N reacts with sodium, Na. Sebatian L, C4H»Br menjalani tindak balas penukargantian dengan ammonia, NH3 untuk menghasilkan butan-2-amina. Tindak balas bagi sebatian L dengan magnesium, Mg dalam ether menghasilkan sebatian M. Tindak balas hidrolisis bagi sebatian L dengan air, H2O menghasilkan sebatian N. Sebatian P dihasilkan apabila sebatian N bertindak balas dengan natrium, Na. (i) Draw the structural formula of compounds L, M, N and P. Lukiskan formula struktur bagi sebatian L, M, N dan P. (ii) Name the type of chemical reaction for the formation of compound N.arrow_forward(a) Draw the three isomers of benzenedicarboxylic acid.(b) The isomers have melting points of 210 °C, 343 °C, and 427 °C. Nitration of the isomers at all possible positions was once used to determine their structures. The isomer that melts at 210 °C gives two mononitro isomers. The isomer that melts at 343 °C gives three mononitro isomers. The isomer that melts at 427 °C gives only one mononitro isomer. Show which isomer has which melting point.arrow_forward.
