Hey can someone tell me why the answer is not A since it have the greatest electronegativity difference?
Explain which of the following pairs will be most likely to form an ionic bond.
A Be and F
B Si and O
CN and Cl
D K and S
Consider the difference in electronegativity of each pair:
C 3.0 and 3.2
D 0.8 and 2.6
A 1.6 and 4.0 B 1.9 and 3.4
Ans)D has the greatest difference, so the compound K,S will be the most ionic.
If I remember this questions from 2020 one of my students asked me there and I think it was a mistake in the book itself, but there aren’t many mistakes at all
Hi!
Could it be because BeF is joined together by a dative covalent bond rather than ionic?
hey could you elaborate please, why you think it should be covalent rather than ionic? (I googled it but I still can’t wrap my head around it)
Hi
yes BeF2 is a covalent compound however im not sure why
