What is its role of trityl tetrafluoroborate in the below experiment and what would be the byproduct of the reaction?
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. What is the role of adding CH,COOH and NaOH during the coupling reaction (in this experiment)?
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...
