Question:

Lithium aluminium hydride reacts with silicon tetrachloride to form?

LiCl,AlCl3andSiH4

LiCl,AlH3andSiH4

LiH,AlCl3andSiCl2

LiH,AlH3andSiH4

Solution:

Lithium aluminium hydride reacts with silicon tetrachloride to form LiCl (lithium chloride), AlCl₃ (aluminium chloride), and SiH₄ (silane). The reaction can be represented by the following equation:

4LiAlH₄ + SiCl₄ → 4LiCl + 4AlCl₃ + SiH₄
