Which property is not shown by covalent compounds?
Correct answer: B. They are more reactive than ionic compounds
- A. They are present in the gas, liquid or solid state
- B. They are more reactive than ionic compounds
- C. They show resonance and isomerism
- D. They have low melting points and boiling points as compared to ionic compounds
Explanation
The ionic compounds exist in the form of ions in an aqueous solution. The chemical reaction between ions occur rapidly.Since, there is no strong electrical force to speed up a chemical reaction (like in ionic reaction),the covalent bonds are generally much slower to react as they involve bond breaking and making of bonds.Covalent bonds react in a variety of ways and their reactivity depends upon the way a reaction proceeds and the kind of a reaction ,so the statement given in option 'B' is not true about covelant compounds and ultimately is the correct answer to this question.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
