- (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_forwardGive reasons for the following :(i) Phenol is more acidic than methanol.(ii) The C—O—H bond angle in alcohols is slightly less than the tetrahedral angle (190°28′).(iii) (CH3)3C—O—CH3 on reaction with HI gives (CH3)3C—I and CH3—OH as the main products and not (CH3)3C—OH and CH3—I.arrow_forwardFor the generic ester RC(O)OR′, which bond will hydrolyzeunder basic conditions?(a) the R¬C bond (b) the C“O bond (c) the C¬O bond(d) the O¬R′ bond (e) more than one of the abovearrow_forward
