Interpretation:
The names of the given molecular compounds are to be determine.
Concept Information:
If the two elements in a binary compound are non-metals, then it is a molecular compound.
Rules for naming molecular compounds:
Replace the ending of the second element with “ide”.
While naming molecular compounds prefixes are used to indicate the number of a given element present in the compound like ” 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.
In case 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. For example, one oxygen would be monooxide, but instead it’s monoxide. The extra o is dropped.
In case of the compound having only one of the first element, prefix can be dropped. For example, CO is carbon monoxide, not monocarbon monoxide.
The more electropositive atom is written first, followed by the more electronegative atom with an appropriate suffix. For example, H2O (water) can be called dihydrogen monoxide (though it’s not usually).
