Verified Solution

Answer & Solution

Correct Answer

(A) \(\mathrm{SiO}_{2}\)

Step-by-step Solution

Detailed explanation

Monosilane \(\left(e g, S i H_{4}\right)\) on coming in contact with air burns with a luminous flame producing vortex ring. These rings are of silica.
\(\mathrm{SiH}_{4}+3 \mathrm{O}_{2} \longrightarrow \mathrm{SiO}_{2}+2 \mathrm{H}_{2} \mathrm{O}\)
