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. For cyclic aldehydes and ketones, the percentage of keto form increases as the ring size increases. This is because the angle strain increases in small cyclic rings. The bond angle for a sp 2 hybridized carbon atom is larger than it is for a sp 3 hybridized carbon atom.

Question

Given the following concentrations for a system, calculate the value for the reaction quotient: Cl2(g)+ CS2(g) ⇌ CCl4(g)+ S2Cl2(g) Cl2 = 31.1 atm CS2 = 91.2 atm CCl4 = 2.12 atm S2Cl2 = 10.4 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.
