Question

41. The correct name for MgF2 is _

a. magnesium difluoride
b. monomagnesium difluoride
c. manganese bifluoride
d. magnesium fluoride

Answer 1

The correct IUPAC name for MgF2 is magnesium fluoride, without the use of prefixes such as 'mono-' or 'di-' because magnesium is in its standard oxidation state and is a common cation.

Step-by-step explanation:

The correct name for MgF2 is magnesium fluoride. When naming binary ionic compounds like this one, the metal (magnesium in this case) keeps its name, and the non-metal (fluorine) changes its ending to '-ide'. Here, magnesium is in its standard oxidation state of +2, and since it's a common cation, its name doesn't need a prefix. Fluorine is -1, but since there are two atoms to balance out magnesium's +2 charge, 'di-' is not used in the name. Thus, the correct option is d. magnesium fluoride.

Answer 2

d. magnesium fluoride

Step-by-step explanation:

Magnesium fluoride is binary ionic compound composed of only two element magnesium and fluorine.

When naming these compounds the name of metal or cation is written first and anion is written after the cation. The anions are non meals.

The anion name is end with suffix " ide".

such as magnesium fluoride.

The oxidation number of metal i.e magnesium is +2. In given compound the oxidation state of fluorine is -1 that's why two atoms of fluorine are attached with one magnesium atom.
