Which of the following statements is false about the hydrides of boron and silicon?
They are covalent compounds.
They are electron-deficient.
They have a tetrahedral structure.
They are highly stable.
Boron and silicon hydrides are not highly stable due to their electron-deficient nature. They are covalent compounds with a tetrahedral structure. Hence option D is correct.
Option(1) Boron and silicon hydrides are covalent compounds. Hence option 1 is incorrect.
Option(2) Boron and silicon hydrides are not highly stable due to their electron-deficient nature. Hence option 2 is incorrect.
Option(3) Boron and silicon hydrides are covalent compounds with a tetrahedral structure.. Hence option 3 is incorrect.
