Interpretation:
The molecular formula of the given compounds needs to be determined.
Concept introduction:
1. Molecular formula can be written by taking the numbers (which are written as the prefixes to the respective elements in the nomenclature) and adding them as suffixes in the formula.
2. Acids containing binary elements are named as hydro
3. Acids containing poly atomic groups are named as stem
Answer to Problem 35SSC
Molecular formula of compounds will be:
Iodic acid
Disulfur trioxide
Dinitrogen monoxide
Hydrofluoric acid
Explanation of Solution
Iodic acid is a poly atomic acid hence stem
Balancing the charges will give formula as
Disulphuric trioxide’s formula can be written using the concept (1)
disulphur
Dinitrogen monoxide's formula can be written using the concept (1)
dinitrogen
Hydroflouric acid is a binary element containing acid in which hydrogen is cation and fluorine is anion. Thus, the formula is
Or,
HF
Iodic acid
Disulfur trioxide
Dinitrogen monoxide
Hydrofluoric acid
