Which of the following is not the consequence of H-bonding?

Options

A. Glycerol is more soluble in water than ethanol.
B. Boiling point of `C_(2)H_(5)OH` is higher than `CH_(3)-O-CH_(3)`.
C. p-nitrophenol has higher boiling point than o-nitrophenol
D. HCl is water soluble due to H-bonding

Answer

To determine which of the following is not a consequence of hydrogen bonding, we will analyze each option step by step.

### Step 1: Analyze Option A - Glycerol and Ethanol Solubility
- **Glycerol (C3H8O3)** has three hydroxyl groups (-OH), which can form multiple hydrogen bonds with water.
- **Ethanol (C2H5OH)** has one hydroxyl group, which can form fewer hydrogen bonds.
- Since glycerol can form more hydrogen bonds with water than ethanol, it is more soluble in water.
- **Conclusion:** This is a consequence of hydrogen bonding.

### Step 2: Analyze Option B - Boiling Point of Methanol vs. Ether
- **Methanol (CH3OH)** can form hydrogen bonds due to its hydroxyl group.
- **Ether (e.g., Dimethyl ether, CH3OCH3)** does not have hydrogen bonding between its molecules.
- The presence of hydrogen bonding in methanol leads to a higher boiling point compared to ether.
- **Conclusion:** This is a consequence of hydrogen bonding.

### Step 3: Analyze Option C - Boiling Points of Para-nitrophenol vs. Ortho-nitrophenol
- **Para-nitrophenol** can form intermolecular hydrogen bonds, leading to a higher boiling point.
- **Ortho-nitrophenol** tends to form intramolecular hydrogen bonds, which reduces its boiling point.
- The difference in boiling points is due to the type of hydrogen bonding present.
- **Conclusion:** This is a consequence of hydrogen bonding.

### Step 4: Analyze Option D - HCl in Water
- **HCl (Hydrochloric acid)** does dissolve in water, but it does not form hydrogen bonds with water.
- The hydrogen in HCl is attached to chlorine, which is not considered an active hydrogen for hydrogen bonding.
- HCl's solubility in water is due to ionization rather than hydrogen bonding.
- **Conclusion:** This is NOT a consequence of hydrogen bonding.

### Final Answer
The option that is not a consequence of hydrogen bonding is **D: HCl in water soluble due to hydrogen bonding**.
