A compound having molecular formula `C_(4)H_(10)O` can show

Options

A. Metamerism
B. Functional isomerism
C. Chain isomerism
D. Position isomerism

Answer

To determine the types of isomerism a compound with the molecular formula \( C_4H_{10}O \) can exhibit, we will analyze the possible structural variations of the compound.

### Step-by-Step Solution:

1. **Identify the Compound Type**:
The molecular formula \( C_4H_{10}O \) indicates that the compound can either be an alcohol or an ether. This is because it fits the general formula for alcohols and ethers, which is \( C_nH_{2n+2}O \).

**Hint**: Check the general formulas for different classes of organic compounds to identify potential functional groups.

2. **Functional Isomerism**:
Since the compound can be an alcohol (e.g., butanol) or an ether (e.g., dimethyl ether), it can show functional isomerism. This is when compounds have the same molecular formula but different functional groups.

**Hint**: Look for compounds with the same formula but different functional groups to identify functional isomerism.

3. **Chain Isomerism**:
The compound can also exhibit chain isomerism. This occurs when the carbon skeleton can be arranged in different ways. For example, butanol can exist as a straight-chain (n-butanol) or branched (isobutanol).

**Hint**: Consider how the carbon chain can be rearranged while maintaining the same number of carbon atoms.

4. **Position Isomerism**:
In the case of alcohols, the hydroxyl (-OH) group can be attached to different carbon atoms. For example, in butanol, the -OH group can be on the first carbon (1-butanol) or the second carbon (2-butanol), leading to position isomerism.

**Hint**: Examine the possible positions of functional groups on the carbon chain to identify position isomerism.

5. **Metamerism**:
Metamerism can occur in ethers where the alkyl groups on either side of the oxygen atom can be different. For example, ethyl methyl ether (C2H5-O-C1H3) and dimethyl ether (C1H3-O-C1H3) are examples of metameric forms.

**Hint**: Consider variations in the alkyl groups attached to the same functional group (like ethers) to identify metamerism.

### Conclusion:
The compound with the molecular formula \( C_4H_{10}O \) can show:
- Functional isomerism (alcohol vs. ether)
- Chain isomerism (straight vs. branched chains)
- Position isomerism (different positions of the -OH group in alcohols)
- Metamerism (different alkyl groups in ethers)
