### Is carbon–sodium bond mainly ionic or covalent?

We all know that carbon mostly forms covalent bonds (almost always) and sodium mostly forms ionic bonds (almost always). But if $\ce{NaOH}$ reacts with ethyne, then $\ce{HC#CNa}$ and $\ce{H2O}$ are ...

### The impossibility of 100% ionic bond

Recently, I read the definition of oxidation state on Wikipedia. It read that a 100% ionic bond is impossible. So what does a 75% ionic and 25% covalent bond mean at all?

### Is beryllium difluoride covalent or ionic?

My textbook says that despite the large electronegativity difference $\ce{BeF2}$ is covalent since the beryllium ion will have too much charge density and it will attract the fluorine electron cloud ...

### Is PbO ionic compound?

In IIT-JAM 2018, There was one question, which one of the following oxides are ionic? There was one option PbO also. According to the official answer key, PbO isn't ionic. Although I know this ...

### Why does a carbocation undergo covalent bonding with, say, chloride, rather than ionic bonding, like what occurs between Na+ and Cl-?

I've been trying to look for an answer for a while but I can't find one. Why does a carbocation accept an electron pair from a nucleophile and form a covalent bond rather than just accepting one ...

### Why isn't water an ionic compound?

If two alkali metal atoms join with an oxygen atom, an ionic bond forms. Since hydrogen has the same number of valence electrons as alkali metals, why can't water be ionic? This is what I'm thinking:...

### I have a question regarding chemical bonds

can NaCl bond be called polar covalent bond? I understand that it's ionic bond but Na is still sharing its electron with Cl. I am confused with Ionic and polar covalent bond.

### Why is the melting point of KBr higher than that of CsCl?

I thought that when compounds have similar forces and charges, the one with the higher molecular weight has the higher melting point. If that is true, then why is the melting point of $\ce{KBr}$ ...

### Is the bond in HF ionic while it is covalent in HCl?

Why would a hydrogen atom "donate" to fluorine in an ionic bond but not in $\ce{HCl}$? Why would $\ce{H}$ and chlorine share instead of $\ce{Cl}$ just stripping it away like $\ce{F}$ does?

### Which has more ionic character, LiF or K2O?

After drawing the structures of both and considering dipole moment, doesn't it seems that all K2O should have more ionic character than LiF? My textbook says its LiF.
