Question
Chemistry Question on Chemical bonding and molecular structure
Ionic compounds are formed most easily with
A
low electron affinity, high ionisation energy.
B
high electron affinity, low ionisation energy.
C
low electron affinity, low ionisation energy.
D
high electron affinity, high ionisation energy.
Answer
high electron affinity, low ionisation energy.
Explanation
Solution
Formation of ionic bond is favoured by (i) low ionisation potentiaI of metal. (ii) greater vaiue of electron affinity of non-metal. (iii) higher value of lattice energy of resulting ionic compound.
