Question
Explain the preparation of silicon tetrachloride.
✓
Answer
1. Silicon tetrachloride can be prepared by passing dry chlorine over an intimate mixture of silica and carbon by heating to $1675 K$ in a porcelain tube.
$
SiO _2+2 C +2 Cl _2 \rightarrow SiCl _2+2 CO
$
2. On commercial scale, reaction of silicon with hydrogen chloride gas occurs above $600 K$.
$
Si +4 HCl \rightarrow SiCl _4+2 H _2
$
