Question

When vapours of SiCl₄ are passed over hot Mg, the product formed is :
(a) MgSiCl₆
(b) SiCl₂ + MgCl₂
(c) Si + MgCl₂
(d) MgSi + Cl₂

Answer 1

Answer:so option (c)

Is correct.

Explanation:

Answer 2

The product formed is (c) Si + MgCl2

- This reaction is an oxidation - reduction reaction (or we can simply say redox reaction).

- SiCl4 is an oxidising agent whereas Mg is a reducing agent.

- Mg replaces Si from SiCl4  vapours at high temperature.

- The reaction can be denoted as follows:

SiCl4 + 2Mg  →   Si + 2MgCl2
