Ba(OH)2
======
Barium hydroxide, an ionic compound composed of the cation barium, Ba 2+, and the polyatomic anion hydroxide, OH -.
Hydrogen molecules are covalently bonded, not ionically. They are sharing a pair of electrons between them: they have an equal claim on those electrons so the bond is 100% covalent. A compound is made of two or more DIFFERENT types of atom, so H2 is not a compound. Water, H2O, is.
It's a sort of funny covalent bond. In BH3, the B-H sigma orbital is unusually high in energy compared to a C-H bond because of the lower nuclear charge of B compared to C, so it wants to find an unusually low energy unoccupied orbital to stabilize the electrons. It finds that in the unoccupied p orbital of another BH3 molecule, so the orbitals overlap and create a 3-center, 2-electron bond. I'm just a student, though, and I'm sure you can find better explanations using Google.
No. H2S is not an ionic compound since hydrogen does not normally forms ionic bonds because it has only one electron. If it donates its electron completely to S the ionic structure of hydrogen no longer seems to exist due to unavailability of any further electrons. Hence, the bond in the said compound is a covalent one but it may show some polar character.
No, B2H6 is not a ionic compound, it is a molecular compound.
Yes!
Rubidium hydride.
Formula: RbH
There is no neutral B2H4 molecule. It is theoretically possible but has never been observed. B2H4^2- does exist, and it has a structure similar to diborane, B2H6.
Diborane is covalent. The bonding may look a little odd because it has bridging hydrogen atoms, which form 3 centre 2 electron bonds.
It's non-polar, apparently.....
Methanol is a polar covalent compound.
It is not possible for the polar covalent compound to have a lower melting point than the non-polar covalent compound because they have ionic bonds.
N2 is non-polar covalent compound
yes CH4 is non polar covalent compound.
I2 is a non-polar covalent compound.
Methanol is a polar covalent compound.
It is not possible for the polar covalent compound to have a lower melting point than the non-polar covalent compound because they have ionic bonds.
N2 is non-polar covalent compound
yes CH4 is non polar covalent compound.
I2 is a non-polar covalent compound.
Non-polar. The electronegativity difference is 0.2 which is non-polar covalent.
Non-polar covalent
yes
Sodium bicarbonate is an ionic compound.
An oxygen molecule has a non polar covalent bond.
H2O is a polar covalent compound. It has a net dipole moment because oxygen is highly electronegative as compared to hydrogen.
It is carbon disulfide, a non-polar covalent compound.
