Identify the following as a primary, secondary, tertiary, or quaternary amine. Primary secondary tertiary quaternary What is the name of the following compound? o-bromophenol m-bromophenol m-bromoaniline o-bromoaniline What is the name of the following compound N-methylaminocyclopentane N-methylcyclopentylamide N-methylcyclopentylamine N-methyl-N-cyclopentylamide What is the name of the following compound ) N-ethylpentylamine N-cyclopentylethylamine 2-ethylpentylamine N-ethylcyclopentylamine What is the name of the following compound? 4- carboxylpentamide 1 -aminopent-4-one 2- carboxylpent-5-amide 5-aminopent-2-one What is the common name for the structure below? quinoline pyrimidine indole pyridine Use Table 12.1 to determine which of the compounds below is the weakest base. Dimethylamine Pyridine Aniline Ammonia Use Table 12.1 to determine which of the compounds below is the strongest base. Ammonia Ethylamine Methylamine Aniline Use Table 12.1 to determine which of the compounds below would form the weakest conjugate acid. Pyridine Aniline Ethylamine Diethylamine Which of the following statements is true regarding basicity of amines? The stronger the base, the more likely an amine is to accept a hydrogen molecule according to Bronsted-Lowry The stronger the base, the more likely an amine is to accept electrons according to Lewis The stronger the base, the smaller the pKa of the conjugate acid Which of the following statements about amines is correct? The amine nitrogen can never be chiral because it can never have four different groups attached to it Most amines are acidic and will therefore form strong conjugate bases Amines tend to have higher boiling points that alkanes of comparable weight because of hydrogen bonding Amine groups are generally found in carbohydrates and fats. Which of the following statements about amines is correct? Amines cannot participate in hydrogen bonding and therefore have fairly low boiling points compared to alkanes of similar molecular weight The amine nitrogen is sp2 hybridized Amine groups tend to be found in proteins An amine which is a strong base will form a strong conjugate acid
