Question
Given the reaction mechanism and the quantities listed below, find the limiting reagent and the theoretical yield of the given reaction:
0.5 grams 2-naphthol (weight: 114.17 g/mol)
0.2 grams KOH (weight: 56.11 g/mol)
30 mL iodoethane (weight: 155.97 g/mol, density: 1.94 g/mL)
Transcribed Image Text:The image depicts a chemical reaction process.
**Reactants:**
1. **1-Naphthol (C₁₀H₇OH):** Illustrated on the left with a naphthalene ring structure and a hydroxyl group (OH) attached.
2. **Ethyl iodide (C₂H₅I):** Shown as a simple ethyl group (C₂H₅) attached to an iodine (I) atom.
**Reagents and Conditions:**
- **Potassium hydroxide (KOH):** Used in this reaction as a base.
- **Ethanol:** Serves as the solvent.
**Reaction Process:**
- The 1-naphthol reacts with ethyl iodide in the presence of potassium hydroxide in ethanol.
**Products:**
1. **Nerolin (Ethyl naphthyl ether):** The main product, shown on the right. It's characterized by an ethyl group (C₂H₅) connected to the oxygen that links to the naphthalene ring.
2. **Water (H₂O):** A byproduct formed during the reaction.
3. **Potassium iodide (KI):** Another byproduct formed in the process.
This reaction showcases the formation of an ether from an alcohol and an alkyl halide, commonly referred to as the Williamson ether synthesis.

He prepares four reaction vessels by adding 160.9 g of solid zinc and 83. mL of 5.0 M sulfuric acid solution to each, and then filling the remainder of the vessel with distilled water. The volume and temperature of each vessel is shown in the table below. Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on. alo Ar initial rate of vessel volume temperature reaction A 1.0 L 14.0 °C В 4.0 L 14.0 °C ? 2.0 L 14.0 °C 8.0 L 14.0 °C v ? 1 (highest) 2 4 (lowest) >arrow_forwardWhich statement about the reaction below is correct? 2A(g) + 5B(g) → 8C(g) + 6D(g) Group of answer choices A is consumed at a slower rate than B is consumed.
