How are hydrogen bonds differnt from covalent and ionic bonds?

Answer 1

Covalent and ionic bonds are chemical bonds also called intramolecular bonds. Hydrogen bonds are a result of a strong dipole-dipole interaction. We call these intermolecular bonds. Hydrogen bonds result when hydrogen is directly bonded to F O or N. hydrogen bonds are also much weaker than covalent or ionic bonds.

Answer 2

A hydrogen bond is a special type of dipole-dipole force that exists between an electronegative atom and a hydrogen atom bonded to Nitrogen, Oxygen or Fluorine. This type of force always involves a hydrogen atom and the energy of this attraction is close to that of weak covalent bonds (155 kJ/mol), thus the name - Hydrogen Bonding. A covalent bond is only 20 times stronger than an intermolecular hydrogen bond. These attractions can occur between molecules (intermolecularly), or within different parts of a single molecule (intramolecularly). The hydrogen bond is a very strong fixed dipole-dipole van der Waals-Keesom force, but weaker than covalent, ionic and metallic bonds. The hydrogen bond is somewhere between a covalent bond and an electrostatic intermolecular attraction. This type of bond occurs in both inorganic molecules (water) and organic molecules (DNA).

Answer 3

hydrogen bonds are attractive forces between molecule, like London dispersion forces

ionic bonds are bond that can easily be broken by disolving the compound in water, they are bonds formed by positive and negative ions attracting each other.

covalent bonds= co- meaning share like cofounders, valent refering to the valence electrons or outer shell electrons= so essientially it is the sharing of electrons from the outer shell of two atoms.

polar means one atom has a stronger pull on the electron being shared and the electron is basically "held" by the stronger(aka more electronegative) atom. this gives the one atom(holding the electron) a partial neg charge and the other a partial pos charge, non polar means that the "pull" is equal from both atoms and the electron stays in the middle between the two atoms, not giving either a partial neg or partial pos charge

Answer 4

Non-metals have too few electrons in their outer shell to be stable.

Metals have too many electrons in their outer shell to be stable.

Electrons are -vely charged.

Protons are +vely charged.

An ionic bond is where a metal gives up a small number of its electrons and gives them to the non-metal so that both now have a full outer shell. This makes the metal +vely chraged (because there are more protons than electrons) and the non-metal -vely charged (because there are more electrons than protons). Opposing charges attract each other, like with magnets, and the metal and non-metal are 'stuck' together. Magnesium oxide for example, Magnesium has two electrons in its outer shell and Oxygen needs two to fill its outer shell.

A covalent bond is where two non-metals 'share' a few of their outermost electrons to make their outermost shells full. Oxygen gas for example, Oxygen needs two electrons to fill its outer shell so both atoms hold onto two of the other atom's electrons (linking arms if you will), making each of their outer shells full.

Answer 5

Hydrogen bonds: are very weak and are generally between hyrogen and oxygen (at times nitrogen, but generally oxygen)

Covalent bonds: bonds that stick to each other and share electrons

Ionic bonds: don't share electrons; a positive ion "sticks" to a negative ion

Hope this helps!

Answer 6

Covalent bonds occur when two or more atoms share an electron (or more than one). Ionic bonds occur when an electron is transferred between two or more atoms that have a large difference in electronegativity (they're not close together on the Periodic Table), and the resulting ions are electrically attracted to one another. Hydrogen bonds are electrical dipole interactions between the positive, hydrogen end of a water molecule and the negative, oxygen end of adjacent water molecules; Hydrogen bonds are what give water the properties of cohesion and surface tension.

Answer 7

Hydrogen bonds are different from covalent and ionic bonds in that they are not an actual type of bond but a form of intermolecular attraction. When hydrogen bonds with a highly electronegative atom such as nitrogen, oxygen, or fluorine it gains a partial positive charge, while the other gains a partial negative charge resulting in a highly polar molecule that can be attracted to similar molecules in a manner similar to that of magnets..

Answer 8

Hydrogen bonds are different from covalent and ionic bonds in that they are type of intermolecular attraction rather than an actual chemical bond. The term is misleading.
