Chapter EH, Problem 36R

Solution

Interpretation : If bromine gas reacts with solid carbon under elevated temperature conditions the products formed are to be predicted.

Concept Introduction : Carbon is present in period 14 of the periodic table which is denoted by the symbol $\text{C}$ . Carbon is a tetravalent element with four valence electrons.

The product formed by reacting bromine gas with solid carbon at elevated temperatures is carbon tetrabromide.

Carbon is unreactive at normal temperatures.

At elevated temperatures, carbon forms carbon tetrabromide with bromine gas.

Carbon tetrabromide is the only product formed.
