Homework Answers
trityl tetrafluoroborate will abstract hydride (H-) from cycloheptatriene unit to convert to stable aromatic tropylium cation unit as shown in above scheme, since trityl tetrafluoroborate abstact proton it will be converted to Ph3CH, therefore biproduct is triphenylmethane

2. Draw the structure of the byproduct that would be formed if the reaction mixture were not kept in an ice bath during the azo coupling reaction. [2 pts) Methyl orange can be synthesized using an azo coupling reaction, which is an example of an electrophilic aromatic substitution (EAS). In an azo coupling, the electrophile is an aryldiazonium salt, and the nucleophile is another electron-rich aromatic compound (typically an aniline or phenol). In this experiment, sulfanilic acid will be converted...

Discuss the polycondensation reaction. Why would water interfere with it? In case experiment failed-explanation is expected. Why it failed? What could be improved. Explain molecular structure vs signal relationship . In your discussion consider the following concepts: polycondensation, functional groups, fibril formation and stabilization (interchain molecular itneractions) , reaction yield and the role of NaOH solution used in the reaction Can you answer these questions based on the Synthesis of Nylon-6,6 using adipoyl chloride and 1,6-hexanediamine
