Q. Monosilane on coming in contact with air burns with a luminous flame producing vortex rings. These rings are of
A) $SiO_{2}$
B) $SiO$
C) $Si$
D) $H_{2}SiO_{3}$
Explanation
(a)
Monosilane $(e.g.,\ SiH_{4})$ on coming in contact with air burns with a luminous flame producing vortex ring. These rings are of silica.
$\ \ \ \ \ \ \ \ \ \ \ SiH_{4} + 2O_{2} \rightarrow SiO_{2} + 2H_{2}O$
