(ii) `-A-B-B-A-A-A-B-A-`

Options

A. (i) Homopolymer, (ii) Copolymer
B. (i) Natural polymer, (ii) Synthetic polymer
C. (i) Linear polymer, (ii) Branched polymer
D. (i) Fibre , (ii) Elastomer

Answer

To solve the question of identifying the type of polymers given the structures, we will analyze each polymer step by step.

### Step 1: Analyze Polymer (i) `-A -A -A -A -A -A-`

1. **Identify the repeating unit**: The polymer consists solely of the monomer "A" repeated multiple times.
2. **Determine the type of polymer**: Since all the repeating units are the same (only "A"), this polymer is classified as a **homopolymer**.

### Step 2: Analyze Polymer (ii) `-A -B -B -A -A -A -B -A-`

1. **Identify the repeating units**: The polymer consists of two different monomers, "A" and "B", in a specific sequence.
2. **Determine the type of polymer**: Since this polymer is made from two different monomers (A and B), it is classified as a **copolymer**.

### Conclusion:
- The first polymer `-A -A -A -A -A -A-` is a **homopolymer**.
- The second polymer `-A -B -B -A -A -A -B -A-` is a **copolymer**.

### Summary of Types:
- **Homopolymer**: A polymer made from one type of monomer (e.g., `-A -A -A -A -A -A-`).
- **Copolymers**: A polymer made from two or more different types of monomers (e.g., `-A -B -B -A -A -A -B -A-`).
