Question

Among the NaF,Nacl,NaBr,Nal which is the most covalent and why?​

Answer 1

NaI is the most covalent due to small size of cation and large size of anion.

Explanation:

• Covalent bonds are defined as the bonds which exists due to sharing of electrons between the combining atoms.

• According to Fajan's rule, smaller is the size of cation and larger the size of anion more covalently they will be bonded together.

• Therefore in NaI, size of sodium ion is smaller and size of iodine ion is the largest. Hence, there exists a covalent bond between sodium and iodine.
