Question

If the electronegativity difference between bonded atoms is exactly 1.7, the nature of the bond formed is :

• A. > $50\%$ ionic
• B. < $50\%$ ionic
• C. $50\%$ ionic and $50\%$ covalent
• D. $100\%$ ionic

Answer 1

The correct option is C $50\%$ ionic and $50\%$ covalent

If the electronegative difference is $>1.7$ then its nature is ionic and $<1.7$ then its nature is covalent and if its equal to $1.7$ then nature of bond will be $50\%$ ionic and $50\%$ covalent.

Hence, the correct option is $\text{C}$
