What is the difference in electronegativity between H and F in HF?
The electronegativity difference between hydrogen (H) and fluorine (F) in the HF molecule is 1.9. This high difference in electronegativity gives the HF molecule its polar characteristic, with fluorine being more electronegative and attracting electron density towards itself, resulting in a partial negative charge on fluorine and a partial positive charge on hydrogen.
Which of the following examples is a molecule with a covalent bond (Use the electronegativity values from the periodic table link to help you answer this question.)?
B. Co
Because the electrons in a molecule of hydrogen fluoride are more strongly pulled toward the fluorine atom is the molecule nonpolar?
No, despite the electronegativity difference between hydrogen and fluorine, hydrogen fluoride is a polar molecule due to the uneven distribution of electron density caused by the fluorine atom's higher electronegativity. This results in a partial negative charge on the fluorine atom and a partial positive charge on the hydrogen atom, making the molecule polar.
What is the polarity of the HCl molecule due to?
The HCl molecule is polar due to the difference in electronegativity between hydrogen and chlorine. Chlorine is more electronegative than hydrogen, causing the electrons in the bond to be unequally shared, resulting in a net dipole moment.
What is ethyl alcohol's electro negativity?
Ethanol (C2H6O) is a polar molecule containing a methyl group and a primary alcohol. The electronegativity of a carbon atom is 2.5, hydrogen is 2.2, and oxygen is 3.5. Summing up the electronegativity of the two groups and finding the difference gives an electronegativity value of 3.5 for ethyl alcohol.
What is the electronegativity difference between the bonded atoms C-H?
The electronegativity difference between carbon (C) and hydrogen (H) is about 0.4. Carbon has an electronegativity value of 2.55, while hydrogen has a value of 2.20. This relatively small electronegativity difference means that the C-H bond is considered nonpolar.
What is the charge of cyclohexane?
Cyclohexane has no charge. It is a compound, not an ion.
Is hydrogen chloride a nonpolar molecule?
I think you mean HCl and Cl (with an L). HCl is polar because there is a difference in electronegativity between hydrogen (H) and chlorine (Cl). Cl on its own is a single atom and is not bonded to anything for there to be a difference in electronegativity. Cl2 is nonpolar because there is no difference in electronegativity between atoms of the same element.

What makes the bond in hydrogen fluoride molecule a polar bond?
Hydrogen has a low electronegativity while fluorine has an extremely high electronegativity.
Is water polar because the hydrogens or because the electronegativity?
Water is polar because of the difference in electronegativity between oxygen and hydrogen, and the shape of the molecule. Each H-O bond is polar, and, because of the large, electronegative oxygen atom, the molecule is bent so that the partially negative oxygen atom is at one pole of the molecule and the partially positive hydrogen atoms are at the opposite pole of the molecule.
Because the electrons in a molecule of hydrogen fluoride are more strongly pulled toward the fluorine atom is the molecule nonpolar?
No, despite the electronegativity difference between hydrogen and fluorine, hydrogen fluoride is a polar molecule due to the uneven distribution of electron density caused by the fluorine atom's higher electronegativity. This results in a partial negative charge on the fluorine atom and a partial positive charge on the hydrogen atom, making the molecule polar.

What happens When is bromine is added to cyclohexane?
When bromine is added to cyclohexane, bromination of the cyclohexane molecule may occur. This involves the substitution of a hydrogen atom in the cyclohexane ring with a bromine atom. This reaction can result in the formation of a new compound with bromine substituents on the cyclohexane ring.
What is ethyl alcohol's electro negativity?
Ethanol (C2H6O) is a polar molecule containing a methyl group and a primary alcohol. The electronegativity of a carbon atom is 2.5, hydrogen is 2.2, and oxygen is 3.5. Summing up the electronegativity of the two groups and finding the difference gives an electronegativity value of 3.5 for ethyl alcohol.
Is h2s a polar molecule?
Yes and no. The difference in electronegativities of hydrogen (2.2) and sulfur(2.6) is exactly the same as that between hydrogen and carbon(2.6). The C-H bond is viewed as non-polar and so, therefore, should the H-S bond. However, due to the fact that there IS a difference in electronegativities, there is a small degree of ionic character (polarity) in both bonds. The boiling point of hydrogen sulfide (213K) strongly suggests the molecule be deemed non-polar, despite what some sources say.
