Reason: AgCl having least covalent character and Ag having least ionic character.
Which of the following is least ionic nature?
As we move left to right in a period, the size of the cation decreases and ionic character also decreases. Among Ag,K,Ca,Ba , the compound that is present in the d block is Ag whereas K,Ca,Ba they are all present in s block. Therefore, AgCl is least ionic among the above options.
Which one of the following is least ionic c2h5cl?
Answer. Explanation: It is because KCl is a covalent compound.
Which of the following is least ionic CA?
The A gCl which posses least covalent character due to the forces in the lattice are strong and Ag is transition metal having least ionic character.
Which of the following is most ionic?
Fluorine is the element which has highest electronegativity. So, the Al-F bonds will be ionic and this molecule will be most ionic.
Which is more ionic LiCl or becl2?
BeCl 2 is more covalent than LiCl . As per the Fajan’s rule, more the polarisation, more will be the covalent character.
Which one shows the correct order of increasing ionic character?
Apply Fajans’s rule, charge on the cation is same and tha anion is common in all the compounds, so the size of cation will decide the ionic character or the ionic character down group 2, increases.
Why CuCl is more covalent than NaCl?
NaCl is an ionic compound whereas CuCl is a covalent compound. ... Cucl is more covalent than nacl, because cu has a pseudo noble gas structure of the same size as that of na & cucl , because it has 18 electrons in the outermost shell than NaCl, which has 8 electrons.
Which one is the strongest bond?
In chemistry, covalent bond is the strongest bond. In such bonding, each of two atoms shares electrons that binds them together. For example, water molecules are bonded together where both hydrogen atoms and oxygen atoms share electrons to form a covalent bond.
Which of the following is least ionic radius?
The Mg+2 has least ionic radius. It act be consistent with Pauling radii and use for calculating the ionic radius as magnesium +2. It has been separated from the crystals and will be less than sum of soft sphere radii.
Which bond is present in n2o5?
As we know that both nitrogen and oxygen are metals, so there are four covalent bonds present in nitrogen pentoxide.
Why is AlCl3 covalent and AlF3 ionic?
Hence, by fajan’s rule AlCl3 has more covalent character , as compared to AlF3 which has less covalent and more ionic character. Since, AlF3 has ionic character or it forms an ionic bond, it cannot be electron deficient. As in ionic bonds we know that one atom donates electrons to another.
What is the ionic character of KI?
Potassium iodide (KI) forms an ionic bond. Potassium and iodine have very different electronegativities. The two atoms would form an ionic bond since ionic bonds form between atoms with a large difference in electronegativity (difference>1.7 using the Pauling scale will result in an ionic bond).
How do you find which is more ionic?
the highest and most center one will be the most ionic compound . It is important to rememebr that bonding is a spectrum. Compounds are not either ionic or covalent but most are something inbetween. The procedure above shows how to distinguish between two ionic compounds.
Which of the following is most ionic p2o5?
Mno is the most ionic compound. Mno has the lowest magnitude positive charge hence Mno is the most ionic compound. Magnitude of the positive charge is directly proportional to Polarization power , directly proportional to Covalent character and indirectly proportional to ionic character.
Which is more ionic LiCl or RbCl?
Note: In the given problem, after rubidium chloride lithium chloride will have the maximum ionic character and then magnesium chloride. Lithium will be more ionic because down the group electronegativity decreases and magnesium is placed below to the lithium.
