10 B Nucleophilic Substitution Reactions Made Simple: SN1 and SN

What is the topic discussed in this session?

• The session's agenda
• Nucleophilic Substitution Reactions

• The speaker's background
• The location of the event

What type of carbon does a nucleophile attack in a nucleophilic substitution reaction?

• Carbon attached to a hydrogen atom
• Electrophilic carbon (carbon bonded to a leaving group)
• Carbon in a double bond
• Nucleophilic carbon (carbon with a negative charge)

What happens in a nucleophilic substitution reaction?

• A nucleophile adds to a molecule without replacing any groups.
• A leaving group is replaced by another leaving group.
• A nucleophile reacts with a solvent instead of a substrate.
• A strong nucleophile substitutes a weak nucleophile

Nucleophilic substitution reactions are classified into which two main types?

• SN1 and SN2
• SN3 and SN4
• SNi and SNe
• SN1 and SNi

In SN2 reactions, the nucleophile attacks:

• the leaving group
• the solvent molecule
• the nucleophile's own atom
• From the opposite side of the leaving group

What is the transition state in an SN2 reaction?

• The transition state is a stable intermediate with no bonds formed.
• The transition state occurs after the leaving group has departed.
• The transition state is a low-energy state where the nucleophile is fully bonded.
• An imaginary, unstable state

What order of kinetics does an SN2 reaction follow?

• Second order

• First-order kinetics
• Zero-order kinetics
• Third-order kinetics

What type of stereochemical change occurs in SN2 reactions?

• Complete inversion

• Retention of configuration
• Racemization
• No change in configuration

Which type of solvent favors SN2 reactions?

• Polar aprotic solvents
• Aqueous solvents
• Non-polar solvents
• Polar protic solvents

In SN1 reactions, which type of alkyl halide is most reactive?

• Vinyl halides
• Secondary alkyl halides
• Tertiary alkyl halides
• Primary alkyl halides
