Question 32
Write the formulae of chlorides of Eka-silicon and Eka-aluminium, the elements predicted by Mendeleev.

Open in App

Solution

The Eka- silicon is germanium and Eka- aluminium is gallium. Germanium has valency 4 and gallium has valency 3. Therefore, the fomula of chlorides formed by these compounds is ${GeCl}_{4}$ and ${GaCl}_{3}$ .
