Does hydrogen have allotropes?
No. Elemental hydrogen only exists as a diatomic molecule.
What determines if a molecule is polar nonpolar or ionic?
The two factors are 1) the polarity of the bonds between the atoms in the molecule, and 2) the shape of the molecule. Basically, if the bonds are non-polar, the molecule is. If the bonds are polar, but the molecule is in such a shape that they cancel each other, the molecule is non-polar. If the bonds are polar and the molecule's shape doesn't cause them to cancel, the molecule is polar.
Is the compound C2H8 polar?
The C2H4 molecule is nonpolar as a whole. The individual bonds in the molecule are moderately polar, but the molecule is symmetrical around its center line, and the polarities of the individual bonds cancel each other out at any visually perceptible distance away from the molecule.
Is BCl4 a polar or nonpolar molecule?
I don't think BCl4 is even a POSSIBLE molecule since boron has only three valence electrons; perhaps you mean BCl3 (which is nonpolar)?
Is Mg(NO3)2 polar or non polar?
MgBr2 is ionic, and so would be considered polar.
Is water the only molecule that is polar?
No, water is not the only molecule that is polar.
Why does a polar molecule dissolve anything?
It doesn't. Only other polar molecules.
Is CH2O not soluble in water?
yes it is becasue water is a polar molecule and therefore, can only disolve another polar molecule such as ch2o
How many isomers of c2h2cl2 are polar?
There are only two polar isomers for c2h2cl2 molecule.
Is hexane polar or non polar?
Hexane is nonpolar. It consists of carbon and hydrogen atoms bonded together in a linear structure, resulting in a symmetrical distribution of electron density and no permanent dipole moment.
Is o-c polar or non polar?
The central oxygen is positively charged, and the molecule is bent at an angle, so it is polar. Since the entire molecule has only oxygens, all bonding is covalent.
What is true about a molecule which contains two polar bonds which have the different degrees of polarity will it always be polar or never be polar or only be polar if it is bent?
Polar if it is bent.
Does hydrogen have allotropes?
No. Elemental hydrogen only exists as a diatomic molecule.
Why is hydrogen peroxide polar?
Hydrogen peroxide is polar due to its angular shape. There are only two cases where a molecule is non-polar, which is when the molecule is pure covalent bond in linear or tetrahedral shape. Hydrogen peroxide is neither therefore it is polar.
Why ozone will not dissolve in water?
Ozone is a non-polar covalent molecule. As water dissolves only polar compounds.
Is the cholesterol molecule mostly non polar or polar and why?
It is MOSTLY non polar because it has 27 carbons arranged in several ring structures, and a side chain. This makes it non polar. The only polar parts of the molecule is an -OH group on one of the ring structures.
How do you account for the observed solubility of naphthalene and sodium chloride in water and ether based on the nature of the bonds that exist in them?
The reason why naphthalene can be dissolve in ether and not in water is because of their polarity. Naphthalene is a non-polar molecule. so it can only dissolve with a non-polar molecule.
