The thermal stability of

\mathrm{C}{\mathrm{F}_4}

View answer and explanation

Correct option: B

More than

\mathrm{Si}{\mathrm{F}_4}\;

Option B (More than

\mathrm{Si}{\mathrm{F}_4}\;

) is correct because the C-F bond is stronger than the Si-F bond due to smaller size and higher electronegativity of carbon.
