Classification of Organic Reactions

What is the classification of an organic reaction if an electrophile is added?

• Nucleophilic

• Electrophilic

• Radical

• Substitution

How are organic reactions classified according to what happens when the reaction is over?

• By the type of catalyst

• By the addition, elimination, or substitution

• By the temperature

• By the pressure

What is the role of a nucleophile in a reaction?

• It donates electrons

• It accepts electrons

• It acts as a solvent

• It acts as a catalyst

What charge do electron-deficient regions typically have?

• Negative charge

• Neutral charge

• Positive or partial positive charge

• No charge

Which of the following is a common feature of nucleophiles?

• They are always positively charged

• They have a lone pair of electrons

• They are always neutral

• They are always negatively charged

What is the significance of the lone pair in a nucleophile?

• It makes the nucleophile positively charged

• It allows the nucleophile to accept electrons

• It allows the nucleophile to form new bonds

• It makes the nucleophile neutral

Which of the following is NOT a characteristic of an electrophile?

• Positive charge

• Attacks electron rich regions

• Negative charge

• Partial positive charge

Which of the following is true about electrophiles?

• They donate electrons

• They accept electrons

• They are neutral

• They repel electrons

What do free radicals seek to do with their unpaired electron?

• Donate it.

• Pair it up.

• Lose it.

• Share it.

Which type of reagents are particles with lone pair electrons and are electron pair donors?

• Electrophiles

• Nucleophiles

• Free radicals

• Acids
