Step-by-step solution

Naming of compounds

A specific set of rules applies while naming chemical compounds. Certain prefixes like di-, tri-, tetra-, etc. are used based on the elements’ count and then their name is mentioned.Acompound’s name ends with “-ide”if they arebinary compounds.

Name of each of the compounds

a) $Te{\mathrm{O}}_2:$Tellurium dioxide.

The compound contains two oxygen atoms bonded with the central tellurium atom.

b) $S{b}_2{S}_3:$Antimony trisulfide.

Three sulfide atoms are bonded with two antimony atoms in the given compound.

c) $\mathrm{G}\mathrm{e}{\mathrm{F}}_4:$Germanium tetrafluoride

The compound contains four fluorine atoms bonded with the central germanium atom.

d) $\mathrm{S}\mathrm{i}{\mathrm{H}}_4:$Silane.

The compound contains four hydrogen atoms bonded with the central silicon atom.

e) $\mathrm{G}\mathrm{e}{\mathrm{H}}_4:$Germanium tetrahydride.

The compound contains four hydrogen atoms bonded with the central germanium atom. Its other name is Germane.
