Why is C-H bond in CH4 stronger than Si-H bond in SiH4?

Answer 1

Well, isn't that just a happy little question? You see, the C-H bond in CH4 is stronger than the Si-H bond in SiH4 because carbon is smaller in size than silicon. This smaller size allows carbon to form stronger bonds with hydrogen atoms, creating a more stable molecule. Just like how a sturdy tree with deep roots can withstand strong winds, the C-H bond in CH4 is resilient and strong.

Answer 2

The C-H bond in CH4 is stronger than the Si-H bond in SiH4 due to the higher electronegativity of carbon compared to silicon. Electronegativity is the ability of an atom to attract shared electrons towards itself in a covalent bond. Carbon has a higher electronegativity than silicon, leading to a greater pull on the shared electrons in the C-H bond, making it stronger. Additionally, the smaller size of carbon atoms compared to silicon atoms allows for stronger overlapping of atomic orbitals in the C-H bond, further contributing to its strength.

Answer 3

It is stronger because the electron configuration of Carbon is 2.4 and of Silicon is 2.8.4. Because more rings are filled by the electrons in silicon the outer shell is further away from the nucleus. Therefore, the attraction between the electrons and protons (electrostatic attraction) in the nucleus is less than in CH4. Hope this helps.

Answer 4

The C-H bond in CH4 is stronger than the Si-H bond in SiH4 because carbon has higher electronegativity than silicon. This causes the C-H bond to be more polarized, resulting in stronger bonds due to greater attraction between the atoms. Additionally, carbon's smaller size leads to better overlap of atomic orbitals, further strengthening the bond.

Answer 5

There is a larger difference in electronegativity between Silicon and Chlorine and therefore is a stonger bond.
