question 34

Multiple Choice

Which of the following statements about nucleophilic aromatic substitution is not true?

• A)Increasing the electronegativity of the halogen increases the reactivity of the aryl halide.
• B)Increasing the number of electron-withdrawing groups increases the reactivity of the aryl halide.
• C)Electron-withdrawing groups stabilize the intermediate carbanion,and lower the energy of the transition state.
• D)When a nitro group is located meta to the halogen,the negative charge of the intermediate carbanion can be delocalized onto the NO₂ group,thus stabilizing it.

Reaction Rate

Reaction rate refers to the speed at which reactants are converted into products in a chemical reaction, usually expressed as the change in concentration per unit time.

Molar Concentration

The amount of a substance (in moles) present in one liter of solution, commonly expressed as moles per liter (mol/L).

Reaction Proceed

The process by which reactants transform into products through chemical changes, influenced by factors like temperature, concentration, and catalysts.

Concentration Effect

The impact that changing the concentration of reactants has on the rate of a chemical reaction.
