Question

Statement (1) : There is ionic bonding in Sodium chloride compound.
Statement (2) : Same elctronegativity is shown by sodium and chlorine atoms.

• A. false, false
  
• B. true, false
  
• C. true, true
  
• D. false, true
  
• E. Statement (1) and statement (2) are true and statement (2) is the correct explanation of Statement (1)

Answer 1

The correct option is B true, false

There is ionic bonding in Sodium chloride compound.
Because..
Different ectronegativity is shown by sodium and chlorine atoms.
Sodium is electropositve whereas chlorine is electronegative.
Hence, the option (B) true, false is the correct answer.
Note: Ionic bond is formed if the atoms involved have electronegativity difference more than 2. In general, the electronegativity difference between 2 to 3.2 corresponds to ionic bond and the electronegatvity difference less than 1.8 corresponds to covalent bond.
