The textbook procedure is asking you to dissolve 1 g of 3-nitrophthalic acid in hydrazine and only then to add the triethylene glycol. in the lab the instructor will tell you to add the triethylene glycol from the very beginning together with hydrazine. what would be a good reason to introduce such change? select one: a. 3-nitrophthalic acid is not readily soluble in aqueous hydrazine but it is soluble in organic solvent, triethylene glycol b. triethylene glycol gives two oh groups to the 3-nitrophthalic acid c. 3-nitrophthalic acid reacts with hydrazine too vigorously if the triethylene glycol is not added d. hydrazine should react with triethylene glycol prior reacting with 3-nitrophthalic acid

The reaction between 3-nitrophthalic acid and hydrazine is highly vigorous. Therefore, the answer is option C.

Explanation:

Triethylene glycol is a high-boiling solvent which necessarily used to contain the synthesis of luminol, which is obtained from the reaction between 3-nitrophthalic acid and aqueous hydrazine. However, this reaction is carried out at a very high temperature, the prior addition of triethylene glycol can allow sufficient reflux for the required completion time without evaporating the solvent fully.

Furthermore, Luminol is an organic compound used to detect metallic ions in Biology. For example, it is used to detect blood traces in forensic investigations.
