Which of the following molecule is having least ionic character?1.FeCl

1.	Which of the following molecule is having least ionic character?1.FeCl22. ZnCl23. MgCl24. NaCl
Answer» Answer: Magnesium chloride molecule is having least ionic character. Explanation: According to Fajan's rule, the smaller is the size of cation and LARGER the size of anion the more will be polarizing power of cation which RESULTS in the formation of covalent bond. As the anion is same, so out of NACL and $MgCl_{2}$ , the NA cation has large size as compared to Mg cation. Hence, NaCl will form more ionic bond and the bond between $MgCl_{2}$ will be less ionic. As we move across a PERIOD, the size of atoms decreases. Hence, Fe and Zn will also form ionic bond with chlorine atom. Thus, it can be concluded that magnesium molecule chloride is having least ionic character.

Answer»

Answer: Magnesium chloride molecule is having least ionic character.

Explanation:

According to Fajan's rule, the smaller is the size of cation and LARGER the size of anion the more will be polarizing power of cation which RESULTS in the formation of covalent bond.

As the anion is same, so out of NACL and $MgCl_{2}$ , the NA cation has large size as compared to Mg cation.

Hence, NaCl will form more ionic bond and the bond between $MgCl_{2}$ will be less ionic.

As we move across a PERIOD, the size of atoms decreases. Hence, Fe and Zn will also form ionic bond with chlorine atom.

Thus, it can be concluded that magnesium molecule chloride is having least ionic character.
