Match the foliowing:
`{:(,"(i)Biodegradble polymer","(p)3-Hydroxybutanoic acid"),(,"(ii)Bakelite","(q)phenol"),(,"(iii)Neoprene","(r)2-chlorobuta-1,3-dience"),(,"(iv)Glyptal","(s)pthalic acid"):}`

Options

A. i-p,ii-q,iii-r,iv-s
B. i-q,ii-p,iii-r,iv-s
C. i-p,ii-q,iii-s,iv-r
D. i-s,ii-r,iii-p,iv-q

Explanation

To solve the matching question, we need to pair each polymer or compound with its corresponding monomer or component. Let's go through each option step by step.

### Step 1: Identify the biodegradable polymer
- The first option is "Biodegradable polymer." The only option that fits this description is **3-Hydroxybutanoic acid (p)**. This is a biodegradable polymer known as polyhydroxybutyrate (PHB), which can degrade naturally without special treatment.

**Match:** (i) Biodegradable polymer → (p) 3-Hydroxybutanoic acid

### Step 2: Identify the component of Bakelite
- The second option is "Bakelite." Bakelite is a synthetic polymer formed from the reaction of **phenol (q)** and formaldehyde. Therefore, it is correctly matched with phenol.

**Match:** (ii) Bakelite → (q) Phenol

### Step 3: Identify the monomer of Neoprene
- The third option is "Neoprene." Neoprene is a type of synthetic rubber that is made from the polymerization of **2-chlorobuta-1,3-diene (r)**. This is the correct match for neoprene.

**Match:** (iii) Neoprene → (r) 2-chlorobuta-1,3-diene

### Step 4: Identify the component of Glyptal
- The fourth option is "Glyptal." Glyptal is a polymer formed from the reaction of **phthalic acid (s)** and ethylene glycol. This makes phthalic acid the correct match for glyptal.

**Match:** (iv) Glyptal → (s) Phthalic acid

### Final Matches:
1. (i) Biodegradable polymer → (p) 3-Hydroxybutanoic acid
2. (ii) Bakelite → (q) Phenol
3. (iii) Neoprene → (r) 2-chlorobuta-1,3-diene
4. (iv) Glyptal → (s) Phthalic acid

### Summary of Matches:
- (i) → (p)
- (ii) → (q)
- (iii) → (r)
- (iv) → (s)
