It is to be explained why the equilibrium percentage of the first given molecule in its keto form is lower than that of the second given molecule, referring to Table 7-1. Concept introduction: In aqueous basic or acidic conditions, ketones and aldehydes exist in rapid equilibrium with a rearranged form called enol form. As a ketone or aldehyde, the species is called the keto form. In the enol form, the species has a carbon atom that is simultaneously a part of a C = C bond, which is a characteristic of alkenes , and is bonded to OH , which is a characteristic of alcohol. These two forms are always in equilibrium with each other, and this is called keto-enol tautomerization. In enol form, the alkyl substitution of the alkene group provides more stability to the molecule.

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.

Manganese(II) Arsenate is insoluble in water at room temperature. (Note: Arsenate = AsO4³-) In the presence of aqueous ammonia, solid Manganese(II) Arsenate becomes more soluble and aqueous tetraamminemanganese (II) ion forms. When solid Manganese(II) arsenate was placed in a 2.00 M solution of ammonia, at equilibrium, 0.308 M of ammonia remains. If the Kf of tetraamminemanganese (II) ion is 250.0, Determine the Ksp of Manganese(II) arsenate Hint: You will have to figure out the Kspf of the overall chemical equation first, then solve for Ksp by using Kf and Kspf
