Organic Chemistry 1 - Quiz - Alcohols, Ethers, and Epoxides - 1
What is the property of an alcohol?
What type of alcohol is 2,3-dimethylbutan-2-ol?
The hydroxy function of 2,3-dimethylbutan-2-ol is on a carbon attached to THREE other carbon atoms ⇒ tertiary alcohol
What is the best method to selectivity synthesize butan-1-ol?
Alcohols can be synthesized by SN reactions from haloalkanes. To avoid competition between SN and E reactions, the halogen atom must be replaced by a better leaving group:
Which of the following will convert butan-2-ol to a ketone?
Carbonyls are formed by oxidation of alcohols using Na2Cr2O7 or PCC
Which of the following reagents is best for converting propanal to an alcohol?
Alcohols can be synthesized by reduction of carbonyls using H- donors (NaBH4 or LiAlH4). LiAlH4 is by far the more reactive of the 2 compounds ⇒ NaBH4 is generally preferred for the oxydation of primary alcohol to avoid any degradation of the compound
Which of the following will convert 2-methylpropan-1-ol to a carboxylic acid?
A carboxylic acid can be formed by overoxydation of a primary alcohol using Na2Cr2O7, H2SO4, H2O
Which of the following will convert butan-2-one to 3-methylpentan-3-ol?
Butan-2-one to 3-methylpentan-3-ol: alcohol synthesis + formation of a Carbon-Carbon bond ⇒ organometallic R-M is used
The added alkyl chain is CH3CH2 (ethyl chain) ⇒ the only possible available conditions are EtMgBr and then H2O
Which of the following will convert bromoethane to pentane?
Bromoethane into pentane: carbon-carbon coupling reactions ⇒ it only works with Gilman reagent
