The correct Answer is:
To analyze the statements given in the question, we can break down the solution step by step. ### Step 1: Analyze Statement 1 **Statement 1:** Tertiary butyl bromide and sodium ethoxide will react to form only ether. - Tertiary butyl bromide (C4H9Br) is a tertiary alkyl halide. When it reacts with sodium ethoxide (C2H5O-), two possibilities arise: 1. **Formation of Ether:** Sodium ethoxide acts as a nucleophile and attacks the carbon atom attached to the bromine, leading to the formation of ether (C2H5O-C4H9) and the release of bromide ion (Br-). 2. **Formation of Alkene:** The bromine can leave first, forming a stable tertiary carbocation (C4H9+). Sodium ethoxide can then act as a base, abstracting a proton from the adjacent carbon, leading to the formation of an alkene (C4H8) and possibly ether as well. Thus, since both ether and alkene can be formed, **Statement 1 is false.** ### Step 2: Analyze Statement 2 **Statement 2:** Ethers are prepared by the reaction of alkoxides with alkyl halides. - This statement is true. The general reaction for preparing ethers involves an alkoxide (RO-) reacting with an alkyl halide (R'X). The alkoxide acts as a nucleophile, attacking the carbon atom of the alkyl halide, leading to the formation of ether (R-O-R') and the release of a halide ion (X-). ### Conclusion - **Statement 1 is false.** - **Statement 2 is true.** ### Final Answer The correct option is: **Statement 1 is false and Statement 2 is true.** ---
