Which is more electronegative O or Se?
Oxygen is more electronegative than selenium.
What happens in a hydrgen bond?
A hydrogen bond is the attractive interaction of a hydrogen atom covalently bonded to a very electronegative atom, such as nitrogen, oxygen or fluorine, to another very electronegative atom in another molecule.The interaction is essentially electrostatic between the small positive charge on the hydrogen atom and the slight negative charge on the N, O or F atom in the other molecule.Examples are the hydrogen bonding in liquid water, alcohols, ammonia and also in solids, ice, solid hydrogen fluoride.In larger molecules that have the right shape the hydrogen bonding can occur within the molecule between a hydrogen atom covalently bonded to a very electronegative atom, such as nitrogen, oxygen and a very electronegative atom in another part of the molecule.
What is the electronegative level of oxygen?
3.44 Very electronegative.
Why carbon is less electronegative than oxygen?
fluorine is the most electronegative atom . therefore atoms closer to fluorine will be more electronegative.
How can you predict the intermolecular forces that would be given a particular molecule?
That will depend on the electronegativity of the atoms involved and the size of the atoms that constitute the compound. There are 3 types of intermolecular forces. Firstly, we have the permanent dipole-permanent dipole interaction. The dipole-dipole interaction is a result of permanent dipoles that exist within the molecule. This is caused by the difference in electronegativity between the 2 atoms. When chlorine meets hydrogen, the highly electronegative chlorine will pull the electrons that is in the covalent bond towards itself, thus forming a delta+ charge at hydrogen and delta- over at chlorine. So, when one highly electronegative atom bonds with a way less electronegative atom, this interaction will occur. Secondly, we have the induced dipole-induced dipole interaction. When 2 atoms meet, electrons repel each other due to the close proximity. Thus, it forms a delta- charge at 1 end of the atom while leaving the other end with a delta+ charge. Plus, electrons move in orbitals, and there are times when they will congregate at one side of the atom. This movement of electrons causes delta- charge to occur at different parts of the atom. Larger atoms are more likely to go through this type of interaction because they have more electrons and hence a higher chance of having congregation. Thirdly, hydrogen bonding occurs when hydrogen (low in electronegativity) bonds with a highly electronegative atom, such as nitrogen, oxygen and fluorine. This causes the same effect as the permanent dipole-permanent dipole interaction, but is characterized by the interaction between hydrogen and a highly electronegative atom. Thus, if the molecule is constituted by these few atoms, such a intermolecular force is likely to act on it.
Define hydrogen bond?
forms when a hydrogen atom covalently bonded to one electronegative atom is also attracted to another electronegative atom
Which element is given first the more electronegative or less electronegative?
fluorine is most electronegative and cesium is least electronegative
Where would you find hydrogen bonds proteins?
The most common bond in hydrogen is a compound one.
Which is more electronegative O or Se?
Oxygen is more electronegative than selenium.

Which element in H20 is more electronegative?
Oxygen is more electronegative than hydrogen.
What is the electronegative level of oxygen?

When will an atom be electronegative?
An electronegative atom gain electrons.
Which is more electronegative Sr or Be?
Sulfur is more electronegative than beryllium.
What is an electronegative?
An electronegative atom is an atom that can attract a bonding pair of electrons from another atom. Fluorine is the most electronegative element.
Why carbon is less electronegative than oxygen?
fluorine is the most electronegative atom . therefore atoms closer to fluorine will be more electronegative.
