Interpretation: From the given compounds binary ionic compounds is to be identified.
Concept Introduction: Binary ionic compounds are ionic compounds comprised of two different types of elements. They are formed when two monoatomic ions bind together by the electrostatic force of attraction.
Answer to Problem 67A
KBr and sodium nitride is the binary ionic compounds among the given compounds. Hence, options a and c are correct.
Explanation of Solution
The compound KBr contains only potassium ions and bromide ions and sodium nitride
Thus, options a and c are correct.
All the other compounds contain polyatomic ions, So,
Thus, options b and d are incorrect.
