Is AlCl3 more ionic than NaCl?

Is AlCl3 more ionic than NaCl?

NaCl is more ionic than AlCl3. In AlCl3, the charge of the cation Al3+ is higher when compared to Na+ while the anion Cl is the same in both the compounds. Therefore, according to Fajan’s rule, AlCl3 is more covalent than NaCl.

Which has the highest covalent character NaCl SiCl4 AlCl3 MgCl2?

MgCl2. Isn’t SiCl4 the answer? Because covalent character is inversely proportional to polarisation and polarisation is inversely proportional to size of the atom. Since out if these, Si is the largest in is have the least polarisation and thus will result in the highest covalent character.

Which is more ionic AlCl3 MgCl2?

According to fajjans rule greater the charge on cation more is the polarisation of anion ,more the polarisation of anion more is the covalent character. Hence AlCl3 is more covalent or we can say MgCl2 is more ionic . Since ionic compounds have higher melting point hence MgCl2 has higher melting point.

Which is more ionic NaCl or cacl2?

If the lattice energy is lesser the ions are easily formed as they are converted to its solid ionic compound easily. Among the sodium chloride and calcium chloride, NaCl has lesser lattice energy than calcium chloride, so NaCl as an ionic compound formation is easy.

Why is AlCl3 a more powerful coagulating agent than NaCl?

By hardly schulze rule, for a negatively charged sol, positively charged ion with higher oxidation state is a better coagulating agent. Since AlCl​3 forms Al3+ ion and NaCl forms Na+1 only, AlCl3 is a better coagulating agent.

Is AlCl3 ionic or molecular compound?

Which is more ionic NaCl or MgCl2?

As a group one element, sodium ionizes more easily that magnesium (a group two element). So sodium ionizes more readily that magnesium. Since the anion is the same in both cases (chloride), this could mean that NaCl is more ionic that MgCl2.

Which is more covalent AlCl3 or MgCl2?

actually, smaller cations have higher charge density due to higher charge density , polarisation will be larger and hence, covent character will be higher. here four ionic compound are ; FeCl2, SnCl2, AlCl3 and MgCl2 . so, covalent character will be maximum in AlCl3 compound.

Which is more ionic AlCl3 or cacl2?

In NaCl both cation and anion have low charges while in AlCl3 the cation Al3+, is of a higher charge than Na+ while the anion is the same in both compounds. According to the Fajan’s rule, AlCl3 is more covalent in nature.

Which is more covalent NaCl or AlCl3?

AlCL3 is more covalent than NaCl. In NaCl, Na will donate one electron to Cl therefore forming an ionic bonding. In AlCl3, Al shares electrons with Cl and forms a covalent bond.

Which of the following is best coagulated by AlCl3 than NaCl?

Is NaCl more ionic than ALCL₃?

Now, there is something to be carefully pointed out: NaCl is “more ionic” than AlCl₃. Indeed, Aluminium chloride is a layered solid that fumes and hisses in moist air (that means, it reacts with water) because the Al-Cl bonds have partial covalent character (its structure calls for Lewis acid properties, too).

Which is the most covalent compound SiCl4?

SiCl4 is most covalent bcoz according to fajan’s rule smaller the cation, larger the anion,more the covalent character.

Why does al form a weak bond while NA form a strong bond?

So Al has greater nucleolus power, that’s why form weak bond. Third less number of electrons in valence shell greater the metallic character and stronger the ionic bond. Na has less number of valence electrons so form stronger ionic bond as compared to Al NaCl bond is stronger than AlCl3 bond. Fast. Simple. Free.

What is the Order of increasing covalent character of NaCl?

The rule concerned in this example is that the cation with the higher positive charge has greater covalent character than the cation with lower positive charge. So the order of increasing covalent character in your example is : NaCl < MgCl₂ < AlCl₃ < SiCl₄
