Chapter 21, Problem 53PS

Interpretation Introduction

Interpretation: The compound C formed in the given  reaction has to be identified.

Concept introduction:

Main group elements are categorized as s-block and p-block elements. The s-block elements include metals belonging to group $\text{1A}$ and group $\text{2A}$ and elements from group $\text{3A}$ to $\text{8A}$ are referred to as p-block elements.

Silicon belongs to group $\text{4A}$ of periodic table and has the highest oxidation number of $+4$. The highest oxidation number is always equal to the group number. Thus, silicon forms compounds with oxides and halides in the oxidation number of aluminium is $+4$.
