`{:(" List-I"," List-II"),((P)"Alcohol",(1)-"ol"),((Q)"Aldehyde",(2)-"ene"),((R ) "Ketone",(3)-"one"),((S)"Alkene",(4)-"al"):}`

Options

A. P-2, Q-4, R-3, S-1
B. P-1, Q-3, R-2, S-4
C. P-2, Q-1, R-4, S-3
D. P-1, Q-4, R-3, S-2

Answer

To solve the problem of matching the functional groups in List I with their corresponding suffixes in List II, we will follow these steps:

### Step 1: Identify the functional groups and their suffixes
We have four functional groups in List I:
- P: Alcohol
- Q: Aldehyde
- R: Ketone
- S: Alkene

We also have the suffixes in List II:
1. -ol
2. -ene
3. -one
4. -al

### Step 2: Match each functional group with its suffix
1. **Alcohol (P)**: The functional group for alcohol is the hydroxyl group (-OH). The suffix for alcohol is **-ol**.

2. **Aldehyde (Q)**: The functional group for aldehyde is the carbonyl group (C=O) with a hydrogen atom attached (CHO). The suffix for aldehyde is **-al**.

3. **Ketone (R)**: The functional group for ketone is also a carbonyl group (C=O), but it is bonded to two carbon atoms. The suffix for ketone is **-one**.

4. **Alkene (S)**: The functional group for alkene is characterized by a carbon-carbon double bond (C=C). The suffix for alkene is **-ene**.

### Step 3: Write down the matches
Now we can summarize the matches:
- P (Alcohol) matches with 1 (-ol)
- Q (Aldehyde) matches with 4 (-al)
- R (Ketone) matches with 3 (-one)
- S (Alkene) matches with 2 (-ene)

### Step 4: Finalize the answer
Thus, the correct matching of the functional groups with their suffixes is:
- P → 1
- Q → 4
- R → 3
- S → 2

This can be represented as:
- PQRS = 1432

### Step 5: Identify the correct option
From the options given, the correct match is option D, which corresponds to 1432.

### Final Answer:
The correct answer is option D: 1432.
