What are (X, Y ) and (Z ) in the following reactions? ( aligned & ( H ₃ C )₃ C - O Na + CH ₃ CH ₂ Br X+ NaBr & ( H ₃ C )₃ C - Br + CH ₃ CH ₂ O a Y+ Z aligned )

Correct answer

2

Step-by-step solution

( ( CH ₃ )₃ C - ONa ⁺+ CH ₃ CH ₂ Br ( CH ₃ )₃ (X) COCH ₂ CH ₃ + NaBr ) These reactions are known as Williamson synthesis where the product (ether or alkene) depends upon the type of halide and alkoxide ion. The reaction (I) involves ( SN ₂ ) attack of (3^ ) alkoxide ion on (1^ ) halide giving ether whereas in reaction (II), a tertiary alkyl halide and primary alkoxide ion are present which gives alkene and alcohol.
