a) 50 mL of CH,CH, Br (bromoethane) and 50 mL of water are poured into a separatory funnel. Bromoethane is a water-insoluble compound with a density of 1.460. The funnel is stoppered and the mixture is shaken vigorously. After standing, two layers separate. Which substance is in which layer? Explain. Bromoethane is more dense than water. The top layer is water and the bottom layer is bromoethane. The top layer is bromoethane and the bottom layer is water. Water is added second. Bromoethane has a higher molar mass than does water.

Question

please help with all the parts in this question, it is practice so I want to have all the parts to study

**Experiment with Bromomethane and Hexane in a Separatory Funnel**

**a) Initial Separation with Bromomethane and Water:**

* 50 mL of CH₃CH₂Br (bromoethane) and 50 mL of water are poured into a separatory funnel. 
* Bromoethane is a water-insoluble compound with a density of 1.460 g/mL.
* The funnel is stoppered and the mixture is shaken vigorously.
* After standing, two layers separate.

**Question: Which substance is in which layer? Explain.**

- Bromoethane is more dense than water.
- The top layer is water and the bottom layer is bromoethane.
- The top layer is bromoethane and the bottom layer is water.
- Water is added second.
- Bromoethane has a higher molar mass than does water.

**b) Addition of Hexane:**

* Into the same funnel is carefully poured 50 mL of hexane (density = 0.660 g/mL) so that the other two layers are not disturbed.
* The hexane forms a third layer.
* The funnel is stoppered, and the mixture is shaken vigorously.
* After standing, two layers separate. 

**Question: Which compound(s) are in which layer?**

**The top layer contains:**

(Answer not provided; typically, the top layer is determined by density, with lighter compounds forming the upper layer.)

**Question 9 of 11:**

The text describes a scenario involving the separation of layers in a mixture where hexane forms a third layer. After the funnel is stoppered, the mixture is shaken vigorously. Following this, two layers separate. The task is to determine which compounds are in which layer.

**Answer Section:**

- **The top layer contains:**
  - [Dropdown menu for selection]

- **The bottom layer contains:**
  - Options:
    - hexane and CH₃CH₂Br
    - water
    - bromoethane
    - water and CH₃CH₂Br
    - hexane and water
    - hexane

This setup involves selecting the correct compound arrangement for each layer after shaking and allowing the mixture to settle, demonstrating principles of liquid-liquid extraction based on density and solubility.
