The mechanism for the formation of o-(hydroxymethyl)benzoic acid when o-phthalaldehyde is treated with a base is to be proposed. Concept introduction: The Cannizzaro reaction takes place by nucleophilic addition of OH - to an aldehyde to give a tetrahedral intermediate, which expels a hydride ion and is thereby oxidized. A second aldehyde group, either within the same intermediate or from another molecule, accepts the hydride ion and thus gets reduced to an alcohol. To propose: The mechanism for the formation of o-(hydroxymethyl) benzoic acid when o-phthalaldehyde is treated with a base.

Question

For the reaction A (g) → 3 B (g), Kp = 0.379 at 298 K. What is the value of ∆G for this reaction at 298 K when the partial pressures of A and B are 5.70 atm and 0.250 atm?

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Interpretation Introduction

Interpretation:

The mechanism for the formation of o-(hydroxymethyl)benzoic acid when o-phthalaldehyde is treated with a base is to be proposed.

Concept introduction:

The Cannizzaro reaction takes place by nucleophilic addition of OH^- to an aldehyde to give a tetrahedral intermediate, which expels a hydride ion and is thereby oxidized. A second aldehyde group, either within the same intermediate or from another molecule, accepts the hydride ion and thus gets reduced to an alcohol.

To propose:

The mechanism for the formation of o-(hydroxymethyl) benzoic acid when o-phthalaldehyde is treated with a base.
