(a)
To determine: The validation of the fact that cis-cycloctene is a meso compound under the original definition, but not under working definition.
Interpretation: The validation of the fact that cis-cycloctene is a meso compound under the original definition, but not under working definition is to be stated.
Concept introduction: The class of diastereoisomers includes stereoisomers that are not enantiomers. They are not mirror images of each other. There are two or more chiral centers generally present in diastereoisomers. Structures of diastereoisomers are not the same, but they are stereoisomers because they differ in the spatial arrangement of atoms.
(b)
To determine: The validation of the fact that a double allene is a meso compound under the original definition, but not under working definition.
Interpretation: The validation of the fact that a double allene is a meso compound under the original definition, but not under working definition is to be stated.

Consider the data below to answer the following questions. Cyanohydrins are important intermediates in the synthesis of α-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated. OH CH-COOH 0 HO CN C H30* C. H H HC N NaOH H₂O C=O 0 cyanohydrin H + NaCN + H₂Oarrow_forward

Show all nonzero formal charges and all nonbonded electrons in each step. Species not involved in a particular step do not need to be included in that step, and resonance forms do not need to be shown.
