How many alcohols with molecular formula `C_(4)H_(10)O` are chiral in nature ?

Options

A. 1
B. 2
C. 3
D. 4

Explanation

To determine how many alcohols with the molecular formula C₄H₁₀O are chiral in nature, we will follow these steps:

### Step 1: Identify Possible Structures
First, we need to identify the possible structural isomers of alcohols that can be formed with the molecular formula C₄H₁₀O. The common alcohols are:
1. Butanol (1-butanol)
2. 2-Butanol
3. Tertiary butyl alcohol (2-methyl-2-propanol)

### Step 2: Analyze Each Structure for Chirality
Next, we will analyze each of these structures to see if they contain a chiral center.

1. **Butanol (1-butanol)**:
- Structure: CH₃CH₂CH₂OH
- Chiral Center: No. The carbon atoms in butanol do not have four different groups attached to them.

2. **2-Butanol**:
- Structure: CH₃CH(OH)CH₂CH₃
- Chiral Center: Yes. The carbon atom bonded to the OH group has four different groups attached: a methyl group (CH₃), an ethyl group (CH₂CH₃), a hydrogen atom (H), and a hydroxyl group (OH).

3. **Tertiary Butyl Alcohol (2-methyl-2-propanol)**:
- Structure: (CH₃)₃COH
- Chiral Center: No. The carbon atom bonded to the OH group has three identical methyl groups (CH₃) and one hydroxyl group (OH), which means it does not have four different groups.

### Step 3: Count the Chiral Alcohols
From our analysis:
- Butanol: Not chiral
- 2-Butanol: Chiral
- Tertiary butyl alcohol: Not chiral

Thus, there is only **one chiral alcohol** among the structures.

### Conclusion
The number of chiral alcohols with the molecular formula C₄H₁₀O is **1**.
