Which of the following is a covalent compound Al2O3 AlF3 AlCl3?

In between AlCl3 and AlF3, cation (Al) is the same both the compound. So the size of anion decides the nature of the compound. Chlorine is larger than fluorine, so the larger sized chlorine gets polarised to a greater extent by aluminium. Hence AlCl3 becomes covalent.

Is Al2O3 a covalent compound?

According to his equation, Al2O3 is slightly nore ionic than covalent. The higher charges on Al and O make their bonding more covalent and with higher Coulombic attraction between the positive and negative ions those of a binary compound involving ions of lower charges (e.g. CaF2, NaCl).

Is AlCl3 a covalent compound?

AlCl3 is covalent where as AlF3 is ionic.

Which of the following is covalent compound?

(d) CCl4 is a covalent compound. CCl4 is a covalent compound as the atoms of carbon and chlorine are characterized by four bonds of non-polar covalent.

Which of the following is a covalent bond Al2O3?

Aluminium oxide (Al2O3) is not an ionic compound. It is a covalent compound.

Why is Al2O3 ionic But AlCl3 covalent?

Al2O3 is ionic due to relative size of oxygen and aluminium and polarizing power of Al, (since we know that aluminium has a charge of +3, provides three electrons) in case of Al2Cl6 & AlCl3 , it seems to be covalent due to similarities like banana bonding & bigger radius of Cl (in compression to oxygen).

Is aluminium nitride ionic or covalent?

Al-N bonds are partially covalent, but they also show some ionic characteristics. structure, 1.633, probably due in part to the ionic characteristics of Al-N bonds [3].

What type of bond is AlF3?

In terms of electron arrangement in the formation of the ionic compound aluminium fluoride, the aluminium donates its three outer electrons to three fluorine atoms forming a triple positive aluminium ion and three single negative fluoride ions.

Why is AlCl3 considered covalent but AlF3 ionic?

Since according to Fajan rule, the ssame cation can polarize a bigger anion (i.e., Cl-) more easily than a smaller anion (i.e, F-) therefore, Cl- can donate electrons back to Al3+ more easily than F-. In other words , AlCl3 is covalent while AlF3 is ionic.

Is AlF3 ionic or molecular?

AlCl3 is covalent while AlF3 is ionic. There is this rule called as Fajan’s rule which states that with increasing size of the anion and with decreasing size of the cation ionic character of the compound decreases while the covalent character increases.

Which of the following most likely a covalent compound?

The correct answer is b. Carbon dioxide comprises carbon, a nonmetal, and two oxygen atoms, which are also nonmetals, forming a covalent compound with covalent bonds connecting the atoms.

Why is AlCl3 a covalent compound and not an ionic compound?

Originally Answered: Why Aluminum Chloride (AlCl3) is a covalant compound and not a ionic compound? Al3+ is highly charged in nature and it can polarise the electron clouds of Cl to a large extent. So, electrons get shared between the two ions. Hence the compound is a covalent one, but the bond is polar covalent. It is what it is.

Why does al form a covalent bond with CL?

Tendency of Al (less electropositive) to lose an electron to form cation and Cl (less electronegative) to accept an electron to form anion is less in this case.Hence bond formation takes place via sharing of electrons leading to covalent compound. Due to high charge on Al.

Is AL3+ a covalent bond or a polar bond?

Hence the compound is a covalent one, but the bond is polar covalent. Al3+ is highly charged in nature and it can polarise the electron clouds of Cl to a large extent. So, electrons get shared between the two ions. Hence the compound is a covalent one, but the bond is polar covalent.

Is AlF3 a covalent or ionic compound?

Fluorine (being very electronegative) will “steal” a lot of electron density from aluminium making the bonds more ionic in nature than covalent. But AlCl3 is covalent due to the low difference in electronegativity So it’s covalent compound. But the probelm is while AlCl3 is covalent, AlF3 is electrovalent or an ionic compound!
