Re: More covalent: BeCl2 or MgCl2? Answer: BeCl2. This is due to the electronegativities of the atoms involved in the bond. ... MgCl2 is more covalent than NaCl because Mg has more positive change and small size.
Answer. Be is much smaller than Ca so it has less tendency to loose electrons,that's why BeCl2 is more covalent. May 14, 2018
The covalent character is determined using Fajan's rule. In the given compounds, the anion is the same and the cations are different. Therefore, MgCl2 is more covalent than NaCl. ...
MgCl2 is an ionic compound because this compound is formed by transfer of electrons between magnesium atom and chlorine atoms. Magnesium atom loses two electrons to form magnesium cation where as each chlorine atom accepts one electron to form chloride ion (anion).
Beryllium Chloride is a covalent compound.
BeCl2 is more covalent than LiCl. As per the Fajan's rule, more the polarisation, more will be the covalent character.
Due to small size and high charge density Be, its polarizing power is maximum, since Be+2 ion essentially pull the electrons cloud from Cl- , such that the electrons pair are effectively shared. This give covalent character to BeCl2.
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. Aug 29, 2018
Applying the second rule we get to know that Iodide ion(I−) size is the largest thereby increasing the covalent character of the compound. The compound with the highest covalent character is CaI2.
The order of increasing covalent character is: NaCl < MgCl2 < AlCl3 < SiCl4, because the charge on the cation increases ii. Increase in size of the anion favours the covalent bond. Among the halides of calcium, CaF2 is more ionic and CaI2 is more covalent.

Barium chloride is an ionic compound composed of one barium cation and two chlorine anions. ... There are two chlorine atoms, so the total oxidation state will be −1⋅2=−2 . Mar 21, 2018
It is highly soluble in water, but less soluble in ethanol. This explains us why BeF2 should be ionic. But since atomic size of beryllium is very small, it will have high charge density & will start to pull the electron cloud of fluorine towards itself. So the bond will become polar covalent bond.

During the formation of BeCl2 , beryllium atom bonds with two chlorine atoms via single covalent bonds. The number of electron pairs around the central atom will be two. No lone pair is found in the molecule. If we analyse this information then we can conclude that BeCl2 has sp hybridization.
NaCl is more ionic compared to the ionic nature of AlCl3. 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.
The covalent character of ionic compound can be determined by Fajans rules,the cation with higher positive charge has greater covalent character than cation with lower positive charge in this SiCl4 having more covalent charcter. Hence the order of increasing covalent character is: KCl< CaCl2<AlCl3<SiCl4.
Smaller the size of cation and larger the size of anion, greater is the covalent character. Among these molecules, lithium cations have smallest size and iodide anions have the greatest size.
hence the bigger the anion the more covalent it is. Hence LiCl is the most ionic whereas LiI is most covalent. Oct 14, 2017
Calculate the % of ionic character of a bond having length = 0.83 Å and 1.82 D as it's observed dipole moment. The example given above is of a very familiar compound called HF. The % ionic character is nearly 43.25%, so the % covalent character is (100 – 43.25) = 56.75%.
MgCl2 is more covalent than NaCl because Mg has more positive change and small size. So according to Fajan's rule more positive charge on cation has more polarising power.
The covalent character decreases as the size of cation increases LiCl > NaCl > KCl > RbCl. Thus LiCl is more covalent than KCl and hence KCl is more soluble in water because of decreased covalent character. Jun 14, 2020
KCl is more ionic because the ionic character increases as down the group while decreases along the period in the periodic table. Also, the bonding in KCl is more ionic than in NaCl. Electronegativity scales also support that NaCl is less ionic when compared to KCl.
The ions are atoms that have gained one or more electrons (known as anions, which are negatively charged) and atoms that have lost one or more electrons (known as cations, which are positively charged). ...

triple covalent bond The carbon monoxide molecule is correctly represented by a triple covalent bond between the carbon and oxygen atoms. One of the bonds is a coordinate covalent bond , a covalent bond in which one of the atoms contributes both of the electrons in the shared pair.
The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. Although the K + ion derives from a strong base (KOH), the NO 2 − ion derives from a weak acid (HNO 2).

Explanation: Along the period, electronegativity (EN) increases and hence as we move from Li → Be → B → C, the electronegativity increases and hence the EN difference between the element and Cl decreases and accordingly the covalent character increases.

Answer: BCl3 is the stronger Lewis acid because the Boron center in BF3 participates in 2p(pi)-2p(pi) back bonding with the Fluorine atoms with a greater overlap thereby reducing it's deficiency. Jan 3, 2019
In contrast, toward weak bases such as CO, BF3 is a stronger Lewis acid than BCl3. ... In contrast, in the formation of a complex with a weak base such as CO, the BX3 is barely distorted from planarity and so the acidity of BF3 is greater than that of BCl3 because the charge on boron is greater in BF3 than BCl3.
CF3- is not stable by resonance due to the absence of d-orbitals on F but CCl3- is stable by resonance due to the presence of d-orbitals on Cl. So, CHCl3 is more acidic than CHF3.
