- $LiCl, AlH_3$ and $SiH_4 $
- $LiCl, AlCl_3$ and $SiH_4$
- $ LiH, AlCl_3$ and $SiCl_2 $
- $LiH, AlH_3 $ and $SiH_4 $
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Lithium aluminium hydride reacts with silicon tetrachloride to form lithium chloride, aluminium chloride and silicon hydride.
$SiCl _{4}+ LiAlH _{4} \rightarrow LiCl + AlCl _{3}+ SiH _{4}$
$SiCl _{4}+ LiAlH _{4} \rightarrow LiCl + AlCl _{3}+ SiH _{4}$

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
