Which is more covalent LiCl or LiF?

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.

Why LiI is most covalent in nature?

Li+ ion is very small in size and has high tendency to distort electron cloud around the negative halide ion. Anion with large size can be easily distorted hence among halides, lithium iodide is the most covalent in nature.

Which is more ionic LiI or LiF?

Lithium fluroide (LiF) is mainly ionic but lithium iodide (LiI) is covalent in nature. I- ion has a bigger size than the F- ion. It can be more readily polarised by Li+ ion than by F- ion. As a result, Li+ and I- ions come quite close and neutralise their charge to a large extent resulting in covalent compound.

Why is LiI is more covalent than LiCl?

Lithium iodide is more covalent than Lithium chloride as the size of I- ion is larger than Cl- ion. Hence I- ion will be more polarised than Cl- ion by the cation Li+ . So LiI is more covalent than LiCl.

Which is more covalent LiCl or LiI Why?

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.

Is LiI covalent bond?

Lithium iodide contains chemical bonds between Li and I atoms. So, the electronegativity difference between Li and I is (2.5-2.1) or 0.4. Hence, the chemical bond between Li and I is covalent. So, lithium iodide is a covalent compound.

Which is more covalent LiCl or LiBr and why?

d.) LiCl < LiBr < 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 lithium halide has most covalent character?

lithium iodide
Fluorine ion is smallest in size and iodine ion is largest. Therefore, among the given metal halides the covalent character of lithium iodide will be highest and lithium fluoride will have least covalent character.

Which of the following has more covalent LiI LiF LiCl LiBr?

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.
