(a)
Interpretation: The formation of the products has to be found via an azo coupling reaction by treating with NaNO2 and HCl.
Concept Introduction:
Aryldiazonium salts on coupling with an activated
To find: Get the product via an azo coupling reaction by treating the compound (a) with NaNO2 and HCl
Find the nature of the given
(b)
Interpretation: The formation of the products has to be found via an azo coupling reaction by treating with NaNO2 and HCl.
Concept Introduction:
Aryldiazonium salts on coupling with an activated aromatic ring give an azo dye which produces a deep color in the final product. This color is due to the extended conjugation in it. This reaction occurs by electrophilic substitution reaction. This method is called an azo coupling. The obtained final compound is known as azo dyes.

- Nonearrow_forward3. Propose a synthesis for the following transformation. Do not draw an arrow-pushing mechanism below, but make sure to draw the product of each proposed step (3 points). CN + En CNarrow_forward3) Propagation of uncertainty. Every measurement has uncertainty. In this problem, we'll evaluate the uncertainty in every step of a titration of potassium hydrogen phthalate (a common acid used in titrations, abbreviated KHP, formula CsH5KO4) with NaOH of an unknown concentration. The calculation that ultimately needs to be carried out is: concentration NaOH 1000 x mass KHP × purity KHP molar mass KHP x volume NaOH Measurements: a) You use a balance to weigh 0.3992 g of KHP. The uncertainty is ±0.15 mg (0.00015 g). b) You use a buret to slowly add NaOH to the KHP until it reaches the endpoint. It takes 18.73 mL of NaOH. The uncertainty of the burst is 0.03 mL.. c) The manufacturer states the purity of KHP is 100%±0.05%. d) Even though we don't think much about them, molar masses have uncertainty as well. The uncertainty comes from the distribution of isotopes, rather than random measurement error. The uncertainty in the elements composing KHP are: a. Carbon: b. Hydrogen: ±0.0008…arrow_forward
