${\rm{CC}}{{\rm{l}}_4}$ does not show hydrolysis but ${\rm{SiC}}{{\rm{l}}_4}$ is readily hydrolysed because:

Electronegativity of carbon is higher than of silicon

IP of carbon is higher than of silicon

Carbon forms double and triple bonds but not silicon

is readily hydrolysed because:

View answer and explanation

Correct option: A

Carbon cannot expand its octet but silicon can expand

The correct answer is A (Carbon cannot expand its octet but silicon can expand) because silicon has available d-orbitals that allow it to expand its octet and accommodate more ligands, facilitating hydrolysis, while carbon does not.
