Let's solve each part in two steps as requested:
---
## a)
### **Step 1: Disconnection**
Identify and draw a squiggly line **between the bond** that, if broken, gives the two starting materials.
- Here, the bond between **C2 and the oxygen** (attached to the ethyl group) is broken.
### **Step 2: Carbon Mapping**
- Map the carbon atoms from the product to the starting materials.
- Benzene ring (C1) is the original ring in the starting material.
- The ethyl group in ethyl acetate becomes the O-ethyl group attached to the carbonyl.
- Number the ethyl group carbons as 11 and 12.
**Final Answer:**
- Disconnection is at the bond between C2 and the O-Et group.
- On ethyl acetate, label the carbonyl carbon as 2.
---
## b)
### **Step 1: Disconnection**
- Break the bond **between the carbonyl carbon (C2) and the oxygen** attached to the isopropyl group.
### **Step 2: Carbon Mapping**
- C1 is the carbonyl carbon in the ester group.
- The isopropyl group in the starting material is derived from the alcohol used in the esterification.
**Final Answer:**
- Disconnection at bond between C2 and the isopropyl oxygen.
- On isopropanol, label the carbon attached to oxygen as 2.
---
## c)
### **Step 1: Disconnection**
- Break the bond **between C2 and OCH3**.
### **Step 2: Carbon Mapping**
- C2 is the carbonyl carbon in the ester group.
- The OCH3 group is from methyl alcohol.
**Final Answer:**
- Disconnection at bond between C2 and OCH3.
- On methyl acetate, label the carbonyl carbon as 2.
---
## d)
### **Step 1: Disconnection**
- Break the bond **between the carbonyl carbon (C2) and Br**.
### **Step 2: Carbon Mapping**
- C2 is the carbonyl carbon of the acyl bromide.
- The bromine is attached to C2.
**Final Answer:**
- Disconnection at bond between C2 and Br.
- On bromoalkane, label the carbon attached to Br as 2.
---
## e)
### **Step 1: Disconnection**
- Break the bond **between C2 and the oxygen attached to the ethyl group**.
### **Step 2: Carbon Mapping**
- C2 is the carbonyl carbon in the ester group.
- The ethyl group (from ethanol) is attached to the oxygen.
**Final Answer:**
- Disconnection at bond between C2 and OEt.
- On ethyl hexanoate, label carbonyl carbon as 2.
---
## f)
### **Step 1: Disconnection**
- Break the bond **between C2 and Br**.
### **Step 2: Carbon Mapping**
- C2 is the carbonyl carbon in the acyl bromide.
- The bromine is on C2.
**Final Answer:**
- Disconnection at bond between C2 and Br.
- On bromoalkane, label the carbon attached to Br as 2.
---
## g)
### **Step 1: Disconnection**
- Break the bond **between C2 and Br**.
### **Step 2: Carbon Mapping**
- C2 is the carbonyl carbon in the acyl bromide.
- The bromine is attached to C2.
**Final Answer:**
- Disconnection at bond between C2 and Br.
- On bromoalkane, label the carbon attached to Br as 2.
---
## h)
### **Step 1: Disconnection**
- Break the bond **between C2 and Br**.
### **Step 2: Carbon Mapping**
- C2 is the carbonyl carbon in the acyl bromide.
- The bromine is attached to C2.
**Final Answer:**
- Disconnection at bond between C2 and Br.
- On bromoalkane, label the carbon attached to Br as 2.
---
### **Summary of Approach**
1. **Disconnection:** Identify and mark the key bond to break to yield the starting materials.
2. **Carbon Mapping:** Assign/label the carbon atoms from the product onto the corresponding atoms in the starting materials.
