Concept explainers
(a)
Interpretation:
The chemical formula for sulphur tetrafluoride has to be written.
Concept introduction:
Naming molecular compounds:
To named binary ionic compounds, first predict the positive ion and then negative ion. The positive ion as named as same element while negative ion taking the first part from its original name and ending with –ide.
Numerical prefix for naming compounds are,
