Question

Which has the stronger bond, the H-C bond in CH₄or the H-Si bond in SiH₄ ?

Explain your answer based on a Lewis structure.

Answer 1

Answer #1

from the lewis structure of CH₄ and SiH₄ the C-H bond in CH₄ is stronger then the Si-H bond in SiH₄

because the electron configration of C in CH₄ is in s and p orbital but in SiH₄ in Si it is n s,p and d orbital

so the attraction in outer shell electron and nucleous is greater in CH4

in SiH₄ the bond length is 1.485 angstrom and in CH₄ bond length is 1.092 angstrom

thats the reason that CH₄ is stronger then SiH₄
