Assertion: Methoxy ethane reacts with HI to give ethanol and iodomethane.
Reason: Reaction of ether with HI follows SN2 mechanism.

The correct answer is option 'A', which states that both the assertion and the reason are true, and the reason is the correct explanation of the assertion.

Explanation:
- Methoxy ethane is an ether with the chemical formula CH3OCH3. It can react with HI (Hydrogen Iodide) to form ethanol (CH3CH2OH) and iodomethane (CH3I).
- The reaction mechanism involved in the reaction between methoxy ethane and HI is an example of nucleophilic substitution reaction, specifically SN2 mechanism.
- In an SN2 (Substitution Nucleophilic Bimolecular) reaction, the nucleophile attacks the carbon atom that is attached to the leaving group (in this case, the iodine atom in HI).
- The nucleophile in this reaction is the hydroxide ion (OH-) which is generated from the HI in the presence of water.
- The hydroxide ion attacks the carbon atom in methoxy ethane, displacing the methoxy group and forming ethanol.
- At the same time, the iodine atom from HI replaces the methoxy group, forming iodomethane.
- The overall reaction can be represented as follows:
CH3OCH3 + HI → CH3CH2OH + CH3I
- In this reaction, the carbon atom in methoxy ethane undergoes inversion of configuration, which is characteristic of SN2 reactions.
- Therefore, the reason given for the assertion is correct. The reaction of ether with HI indeed follows SN2 mechanism.

To summarize, methoxy ethane reacts with HI to give ethanol and iodomethane, and the reaction follows the SN2 mechanism.

Directions : Read the passage given below and answer the following questions :Scuba apparatus includes a tank of compressed air toted by the diver on his or her back, a hose for carrying air to a mouthpiece, a face mask that covers the eyes and nose, regulators that control air flow, and gauges that indicate depth and how much air remains in the tank.A diver who stays down too long, swims too deep, or comes up too fast can end up with a condition called “the bends.” In this case, bubbles of gas in the blood can cause intense pain, even death.In these following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.Assertion : Scuba divers may face a medical condition called ‘bends’.Reason : ‘Bends’ can be explained with the help of Henry’s law as it links the partial pressure of gas to that of its mole fraction.
