Which of the following pairs will form the most stable ionic bond?
The ionic bond between Mg and F is most stable because in these the electrostatic force of attraction is maximum.
Which bond is the most stable?
triple bond
Which one of following pair would form ionic bond?
Answer:(b)Mg and F Since Mg 2+ has a small size and high charge of all the actions so it’s interactions with F will be strongest. Hence the most stable out of all ionic compounds.
Which of the following pair will be formed Electrovalent bond?
As electrovalent bond is formed between elements of large electronegativity difference, so P and Cl can form electrovalent bond.
How many of the following pairs first intermediate is more stable than the second one?
The stability due to resonance is more prominent than the stability due to hyperconjugation. Hence, the first is more stable than the second. Therefore, the correct answer is an option (d)-Ph3C∙, (CH3)3C∙.
Which pair will not form Electrovalent bond?
The bond which is formed by the transfer of electrons between the atoms is called electrovalent bond or ionic bond. Electrovalent bonds are only formed between metals and non-metals. Electrovalent bonds are not formed between two non-metals.
How is Electrovalent bond formed?
Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
Why are Electrovalent compounds soluble in water?
Electrovalent compounds dissolve in polar solvent like water because the forces of attraction between positive and negative charges become weak in water. But since covalent compound are made up of molecules, they do not ionize in water and hence do not dissolve in water.
Why covalent bonds are not soluble in water?
When covalent compounds dissolve in water they break apart into molecules, but not individual atoms. Water is a polar solvent, but covalent compounds are usually nonpolar. This means covalent compounds typically don’t dissolve in water, instead making a separate layer on the water’s surface.
Why are ionic compounds soluble in water and not in kerosene?
Water breaks the ionic bond by hydrogen bonding, as, water itself has a more ionic bond and polar in nature. Many other solvents such as kerosene and petrol are not capable of breaking the ionic bond. Hence, can not dissolve them, and they all have covalent bonds and which are non-polar in nature.
Why are Electrovalent compounds not soluble in kerosene?
why are electrovalent compounds are generally soluble in water but insoluble in solvents like petrol,kerosene? Electrovalent compounds are not soluble in organic solvents, as these solvents do not contain ions which can interact with ions of the electrovalent compounds and thus dissolve them.
What are Electrovalent compounds?
Electrovalent Compounds:- The compounds which contain ionic or electrovalent bonds are Electrovalent or Ionic Compounds. Mainly electrovalent compounds are formed due to the reaction between highly electropositive and highly electronegative atoms.
