**Question 19 of 50**

**Chemical Reaction Analysis:**

A diagram is shown depicting a chemical structure of a chlorinated alkane where a chlorine atom (Cl) is substituted at the terminal carbon. The labeled reactants are:

- **Reagent:** CH₃CCNa
- **Solvent:** DMF (Dimethylformamide)

**Mechanism Options:**

Select the mechanism that best fits the reaction conditions:

A) SN1  
B) SN2  
C) E1  
D) E2  
E) No reaction

**Note:** Tap here or pull up for additional resources.

**Instructions:** Evaluate the reaction conditions and choose the most likely mechanism based on reagent type and solvent. Consider factors such as the leaving group, nucleophile strength, and solvent polarity.

**Question 19 of 50**

**Consider the reaction below. Predict which reaction type is likely to occur.**

A diagram is shown with the structure of a chloroalkane. The compound has a chloro group (Cl) attached to a carbon chain. Below the structure, an arrow points downward to the reagents "CH₃CCNa" and "DMF" which are indicative of the conditions and chemicals involved in the reaction.

- **CH₃CCNa**: This is sodium acetylide, a strong base and nucleophile.
- **DMF**: Dimethylformamide, a polar aprotic solvent that favors bimolecular nucleophilic substitution reactions (SN2).

**Options:**
- A) SN1
- B) SN2

**Explanation:**

In this context, the presence of a strong nucleophile (CH₃CCNa) and a polar aprotic solvent (DMF) suggests that the reaction is more likely to proceed via an SN2 mechanism. The SN2 reaction is characterized by a concerted single-step mechanism where the nucleophile attacks the substrate, displacing the leaving group without the formation of a carbocation intermediate.
