Tollen's reagent is an oxidation agent. What are the products of Tollen's reagent reaction with the following molecule?
Correct answer: D. Propanoic acid and Ag
- A. Propanol and Ag+
- B. Propanoic acid and Ag+
- C. Propanol and Ag
- D. Propanoic acid and Ag
Explanation
It is correct as explained, in the Silver mirror test the product formed is a carboxylic acid and metallic silver. The compound shown is propionaldehyde or propanal hence it forms propanoic acid. Oxidizing agents are substances that become reduced after oxidation of another molecule. Oxidation of an aldehyde will yield a carboxylic acid. The propanal is oxidized to a carboxylic acid and the silver ion is reduced to metallic silver.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.

The figure below is a pedigree that shows the inheritance of a trait, Trait G, in a family. The presence of Trait G in an individual is determined entirely by Gene G. Gene G has 2 alleles: G, which is dominant, and g, which is recessive.Each individual represented in the pedigree was assigned a number (shown below the symbol for the individual) for reference. Scientists determined that the Gene G genotype of Individual 20 is Gg and that the Gene G genotype of Individual 21 is gg. Based on this information, the scientists concluded that Trait G is a dominant trait.Based on the figure, the 2 individuals in which of the following pairs most likely have the greatest genetic similarity across their genomes?
