Question

Which of the following ionic compounds is incorrectly named? BaO, barium oxide TeCl4, tellurium(IV) chloride Fe2O3, diiron oxide Mn3(PO4)2, manganese(II) phosphate Zn(NO3)2, zinc nitrate

Answer 1

Solution :-

While writing the names of the transition metals we use the roman numbers in the parenthesis to mention the oxidation state of the metal.

For the molecular compounds we write the name of the first element and then write the name of the second element with suffix ‘ide’

BaO, barium oxide   =correct

TeCl4, tellurium(IV) chloride = incorrect

Correct name is Tellurium tetrachloride

Fe2O3, diiron oxide = incorrect

Correct name is Iron (lll) oxide

Mn3(PO4)2, manganese(II) phosphate = correct

Zn(NO3)2, zinc nitrate = correct
