Which of the following is more ionic LiF LiCl LiBr LiI?

Fajans rule states that the polarising power is directly proportional to the radius of anion. Hence bigger the anion, the more covalent it is. Size of anion in increasing order is: FLiF is the most ionic whereas LiI is most covalent as Iodine is larger than Chlorine and Bromine.

Which of the following compound has highest covalent character * LiCl LiBr LiF LiI?

Hint: The Lithium ion being small in size can easily distort the electron cloud of an anion thereby leading to the formation of a covalent bond. As the lithium is small in size, higher is the size of anion; higher will be the covalent character in bond.

Which is most ionic LiF?

CsF is more ionic as compared to LiF. Cs has the most electropositive element whereas F has the most electronegative one, so, the difference is the highest.

Which is more covalent LiI or LiBr?

LiCl < LiI < LiBr.

Is LiF more covalent than LiBr?

LiCl is more covalent than LiF because the size of the anion in Lithium Chloride is bigger than cation (as per Fajan’s rule). Hence, the covalent character in LiCl is greater than LiF.

Is LiBr covalent or ionic?

Lithium bromide is an ionic compound of lithium and bromine.

Which is more covalent LiF or LiBr?

LiI has more covalent character. FΘ ion is smaller in size as compoared to IΘ. According to Fajans’ rule, the larger-size anion IΘ is polarised to a greater extent than small size anion, FΘ ion.

Which is the correct order of covalent character LiF LiCl LiBr?

Which of the following is the most ionic?

Thus MnO is the most ionic compound.

Why do lithium halides have partial covalent character?

Lithium-ion has a small size. Hence it can easily distort the electron cloud of the anion. Hence lithium halides have partial covalent character. The anion with a larger size can be easily distorted.

Which one is more ionic LiCl or LII?

Fajans rule states that the polarising power is directly proportional to the radius of anion. hence the bigger the anion the more covalent it is. Hence LiCl is the most ionic whereas LiI is most covalent.

What is the increasing order of covalent character of LiCl LiBr LiI?

The correct increasing order of covalent character of LiCl, LiBr, LiI is: 11th. Chemistry. The s-Block Elements. Characteristics of the Compounds of Alkali Metals.

What is the lattice energy of lithium halides from top to bottom?

So, the lattice energy of lithium halides (LiF, LiCl, LiBr, Li) will be increased from top to bottom i.e from LiF to LiI due to increase in size of the halides. As the size of the halide increases, it requires more energy to combine them together and releases more energy when they are broken down.
