Question: What is the product of the reaction of 1-chloropropane with potassium thiocyanate?

Options:

Correct Answer: propyl thiocyanate

Solution:

The reaction produces propyl thiocyanate through an SN2 mechanism, where the thiocyanate ion acts as a nucleophile.

What is the product of the reaction of 1-chloropropane with potassium thiocyanate?

Step 1: Identify the reactants. We have 1-chloropropane (C3H7Cl) and potassium thiocyanate (KSCN).
Step 2: Understand the type of reaction. This is a nucleophilic substitution reaction (SN2).
Step 3: Recognize the role of the thiocyanate ion (SCN-). It acts as a nucleophile, meaning it will attack the carbon atom bonded to the chlorine in 1-chloropropane.
Step 4: The nucleophile (SCN-) attacks the carbon atom, causing the chlorine atom to leave. This is the key step in the SN2 mechanism.
Step 5: After the reaction, the chlorine atom is replaced by the thiocyanate group, resulting in the product propyl thiocyanate (C3H7SCN).
Step 6: Write the final product. The product of the reaction is propyl thiocyanate.
