Select correct statement(s)

Options

A. Methoxy ethane give iodoethane and methanol with one equivalent anhydrous HI
B. Reaction `CH_(3)+Br+AgFtoCH_(3)-F+AgBr` is known as swarts reaction.
C. optically active alkanol will show total retention of configuration in major product during its reaction with `SOCl_(2)`.
D. Bromoethane gives ethane nitrile with `AgCN` as major product.

Explanation

To solve the question of selecting the correct statements, we will analyze each statement provided in the question one by one.

### Step-by-Step Solution:

1. **Statement 1: Methoxy ethane gives iodoethane and methanol with one equivalent of anhydrous HI.**
- **Analysis:** When methoxy ethane (C2H5OCH3) reacts with anhydrous HI, it undergoes cleavage to form iodomethane (CH3I) and ethanol (C2H5OH), not iodoethane and methanol. Therefore, this statement is **false**.

2. **Statement 2: The reaction CH3 (methyl group) when made to react with Br and EGF gives CH3F and AGBR.**
- **Analysis:** This reaction is indeed known as the Schwartz reaction, where a methyl group reacts with bromine and a metal salt (like AgBr) to produce methyl fluoride (CH3F) and AgBr. Therefore, this statement is **true**.

3. **Statement 3: Optically active alkenol will show total retention of configuration in major product during its reaction with SOCl2.**
- **Analysis:** When an optically active alkenol reacts with SOCl2, it typically undergoes a substitution reaction where the stereochemistry is retained in the major product. Thus, this statement is **true**.

4. **Statement 4: Bromoethane gives ethane nitrile with AGCN as a major product.**
- **Analysis:** When bromoethane (C2H5Br) reacts with silver cyanide (AgCN), it does not yield ethane nitrile (which is propionitrile, C2H5CN) as a major product. Instead, it gives isocyanide (C2H5N), making this statement **false**.

### Conclusion:
Based on the analysis:
- **Correct Statements:** Statement 2 and Statement 3.
- **Incorrect Statements:** Statement 1 and Statement 4.

### Final Answer:
The correct statements are **B and C**.
