In which compound does the bond between the atoms have the least ionic character? 1. hf 2. hcl 3. hbr 4. hi?

HI because the degree of iconic character can be determined based on differences in electronegativity which for HI is .5. Also, Hydrogen Iodide is made up of Hydrogen Halide and a Diatomic Molecule, both of which are non-metals. HF is 1.9, HCL is .9, and HBR is .7; hence HI being the correct answer.

How to distinguish between polar and non-polar molecules/compound? For instance, one that you have not studied before but have t

aleksley [76]

a molecule is polar if we find electronegativity differences between two differing atoms.
when there is large difference between electronegativity values, the more polar the molecule is.
 when the electrons are shared equally between the nuclei.then the molecule is non polar
 in Cl2 moleculethere is no no polar bonds because the electron charge is same on both atoms.
It is therefore a nonpolar molecule.
bonds in hydrocarbon molecules, as hexane, C6H14, are polar,

What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why?

Vikki [24]

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of $N_{2}$ molecule is as follows.

$Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0$ As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.
