What is the molecular shape of silicon tetrabromide? A. linear. . B. pyramidal. . C. tetrahedron. . D. bent triatomic
2 answers:
Answer:
C. tetrahedron
Explanation:
Silicon tetrabromide (SiBr₄)
Valence electrons of silicon = 4
Valence electrons of bromine = 7
The total number of the valence electrons = 4 + 4(7) = 32
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So, the lewis structure is shown in the image below.
Around the central metal atom:-
Number of bond pairs = 4
Number of lone pairs = 0
The formula is .
<u>According to VSEPR theory, silicon tetrabromide has tetrahedron shape to minimize the repulsions. </u>
