Question

Statement 1 : Dimethyl ether and disilyl ether both readily form complexes with trimethyl borane
Statement 2 :

• A. If both Statement $1$ and Statement $2$ are true and the statement $2$ is the correct explanation of the statement $1$
• B. If both Statement $1$ and Statement $2$ are true but statement $2$ is not the correct explanation of the statement $1$
• C. If Statement $1$ is true but Statement $2$ is false
• D. If Statement $1$ is false but Statement $2$ is true

Answer 1

Answer: (D)

In $H_3Si - O - H_3Si$, due to $p\pi - d\pi$ delocalisation, availability of lone pairs on $O$ - atom is decreased and thus disilyl ether does not the react with $B(CH_3)_3$.
