Chemical Bonding And Molecular Structure Question 366
Question: Which compound contains both ionic and covalent bonds-
Options:
A) Sodium nitrate
B) Ammonia
C) Methane
D) Potassium chloride
Show Answer
Answer:
Correct Answer: A
Solution:
- Sodium nitrate is the chemical compound with the formula $ NaNO_3. $ This salt is a white solid which is soluble in water. It is made up of sodium being a metal and nitrogen being a nonmetal. Hence, this compound has both ionic and covalent bonds. Ammonia has a molecular formula of $ NH_3 $ with nitrogen and hydrogen forming covalent bond. Hence, option 2 is correct. Methane has a molecular formula of $ CH_4 $ with carbon and hydrogen forming double covalent bonds. Hence, option 3 is incorrect Potassium chloride has a molecular formula of $ KCl $ with potassium and chlorine forming ionic bond. Hence, option 4 is incorrect
