Question: What is the name of \( {P_4}{O_{10}} \) ?...
What is the name of P4O10 ?
Solution
Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds that contain only two types of elements, the compounds are named by writing the name of the cation first followed by the name of the anion.
Complete answer:
An ionic compound is named first by its cation and then by its anion. The cation has the same name as its element. To name any compound we need to follow the following points:
-Remove the ending of the second element, and add ide just like in ionic compounds.
-When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. mono- indicates one, di- indicates two, tri- is three, tetra- is four, penta- is five, and hexa- is six, hepta- is seven, octo- is eight, nona- is nine, and deca is ten.
-If there is only one of the first elements, you can drop the prefix.
-If there are two vowels in a row that sound the same once the prefix is added, the extra vowel on the end of the prefix is removed.
P4O10 is the dimer of P2O5 , whose chemical name is phosphorus (V) oxide.
Note:
P4O10 itself is not flammable. Just like sulfur trioxide, it reacts vigorously with water and water-containing substances like wood or cotton, liberates much heat and may even cause fire due to the highly exothermic nature of such reactions. It is corrosive to metal and is very irritating – it may cause severe burns to the eye, skin, mucous membrane, and respiratory tract.
