Lewis Acids and Bases Quiz

Questions and Answers

Match the following with their correct definition:

Lewis acid = Contains an empty orbital capable of accepting an electron pair from a Lewis base Lewis base = Any species that has a filled orbital containing an electron pair which is not involved in bonding but may form a dative bond with a Lewis acid Dative bond = Formed when a Lewis acid and base share an electron pair furnished by the Lewis base Nucleophile = Emphasizes the kinetic aspect of reactivity, interchangeable with Lewis base

Match the following with their correct example:

NH3 = Example of a Lewis base (CH3)3B = Example of a Lewis acid NH3 BMe3 = Example of a Lewis adduct Me3B = Capable of accepting a lone pair, example of a Lewis acid

Match the following with their correct terminology:

Nucleophile = Emphasizes the kinetic aspect of reactivity Electrophile = Emphasizes the kinetic aspect of reactivity Lewis basicity = Emphasizes the thermodynamic aspect of Lewis adduct formation Lewis acidity = Emphasizes the thermodynamic aspect of Lewis adduct formation

Match the following with their correct concept:

<p>Lewis acid = Capable of accepting an electron pair to form a Lewis adduct Lewis base = Capable of donating an electron pair to form a dative bond with a Lewis acid Nucleophile = Interchangeable with Lewis base, emphasizes the kinetic aspect of reactivity Electrophile = Interchangeable with Lewis acid, emphasizes the kinetic aspect of reactivity</p> Signup and view all the answers

Match the following with their correct contribution:

<p>Gilbert N. Lewis = Contributions emphasized by the terminology Lewis acid and Lewis base NH3 and Me3B = Involved in a specific chemical reaction forming a dative bond Nucleophilicity = Emphasizes the kinetic aspect of reactivity, interchangeable with Lewis basicity Electrophilicity = Emphasizes the kinetic aspect of reactivity, interchangeable with Lewis acidity</p> Signup and view all the answers
