Question

The product 'P' in the following reaction is CCCC=O \(\stackrel{\mathrm{NaHSO}_{3}}{\longrightarrow}(\mathrm{P})\) (A) Non-crystalline CCCC(O)OC(=O)[O-] , Crystalline (C) CCCC(O)OC(=O)[O-] , Non-crystalline (D) CCCC(O)S(=O)(=O)[O-]

Short answer

The correct product 'P' in the reaction is option (D) with the SMILES notation CCCC(O)S(=O)(=O)[O-].

Step-by-step solution

Understand the reaction and properties of sodium bisulfite

Sodium bisulfite (NaHSO3) is a weak acid that can act as a reducing agent in some reactions. In this case, we have an aldehyde group in the reactant, represented by the SMILES notation "CCCC=O". Sodium bisulfite can react with aldehydes to form bisulfite adducts.

Write balanced equation for the reaction

When the aldehyde represented by "CCCC=O" reacts with sodium bisulfite (NaHSO3), it forms a bisulfite adduct. The balanced equation for this reaction can be written as: \[ \mathrm{CCCC=O + NaHSO_3 \longrightarrow CCCC(O)S(=O)(=O)[O-] + Na^+} \]

Compare the options and determine the correct product

Now, we will compare the products given in the options with the bisulfite adduct formed in the reaction: (A) Non-crystalline: CCCC(O)OC(=O)[O-] - this product is not a bisulfite adduct (B) Crystalline: CCCC(O)OC(=O)[O-] - this product is not a bisulfite adduct (C) Non-crystalline: CCCC(O)OC(=O)[O-] - this product is not a bisulfite adduct (D) CCCC(O)S(=O)(=O)[O-] - this product is a bisulfite adduct Based on the comparison, the correct product 'P' in the reaction is given by option (D), which has the SMILES notation CCCC(O)S(=O)(=O)[O-].
