FREE Master of Chemistry: Organic Chemistry Questions and Answers
Which of the following processes employs lead tetraacetate to dissolve a glycol's carbon-carbon bond?
Criegee glycol oxidation is the process of converting 1,2 diols (or glycols) to aldehydes or ketones using lead tetraacetate [Pb(OAc)4, LTA]. This is accomplished by rupturing the C-C bond between the hydroxyl-carrying carbon atoms. Only anhydrous organic solvents have been documented to trigger this reaction.
Which of the following is not an aromatic hydrocarbon property?
Both electrophilic and nucleophilic aromatic substitutions occur in aromatic hydrocarbons.
Which of the following statements about aromatic hydrocarbon is true?
A delocalized pi bond and a sigma bond are always present between the carbon atoms of an aromatic molecule.
Which of the following organic compound members is the most basic?
Since all other compounds are created by modifying methane, it is both the most basic member of the alkane family and the most basic organic compound.
Which of the following doesn't belong to the category of organic compounds?
Organic compound classes include those that contain substances like carbon, hydrogen, and oxygen. As a result, electro compounds are not an organic compound class.
Which of the following bonds contains a sizable amount of different chemical compounds?
This is as a result of their propensity to transmit electrons.
Organic molecules with the element _________ make up hydrocarbons.
Since only carbon and hydrogen are present in these organic molecules, they are known as hydrocarbons.
Even the function groups can be used to categorize organic substances. Of the following, which is not a functional group?
Isocyanide is not a functional group; it is a substance.
What substance from the list below is utilized to calm the central nervous system?
Acute chloroform intoxication can cause respiratory arrest or a central nervous system depression that can result in mortality. The organic solvent is no longer used as an anesthetic in therapeutic settings, although it is nevertheless used in situations of suicide, homicide, and inhalation for psychoactive effects.
Which of the following ethers-related statements is untrue?
Diethyl ether is extremely non-polar relative to water, hence it will dissolve non-polar molecules and precipitate ionic compounds since like dissolves like. Since opposites attract, your slightly polar organic ether frequently enjoys dissolving your non-polar organic molecules.
Which of the following describes an organic chemical classification?
Open chain and closed chain organic molecules are the two broad categories.
Which of the following is produced when phosphorus tri-iodide is used to cure ethylene glycol?
The unstable red solid phosphorus triiodide (PI3) interacts vehemently with water. Contrary to popular belief, PI3 is commercially accessible and is not inherently unstable. It is frequently used to convert alcohols into alkyl iodides in organic chemistry.
Which of the following complexes contains an organic ligand with a single metal bond?
C2H4, C5H5, and C6H6 are -acceptor ligands, whereas CH3 is the lone -donor ligand.
Which of the following statements about the organic addition reaction is Untrue?
Dehydration is under the category of an elimination reaction, not an addition reaction.
Which of the following doesn't fall within the acid or basic category?
HCl is a potent organic acid, CH3COOH and CH3OH are organic acids, and KCl is a salt.
Which statement regarding transesterification is accurate?
Changing the organic group R′′ of an ester for the organic group R′ of an alcohol is the process of transesterification.
