What are the types of covalent bonds in chemistry?

Answer 1

Covalent bonding includes many kinds of interactions, including o-bonding, TT-bonding, metal-metal bonding, agostic interactions, and three-center two-electron bonds. The term covalent bonddates from 1939. The prefix co- means jointly, associated in action, partnered to a lesser degree, etc.; thus a "co-valent bond", essentially, means that the atoms share "valence", such as is discussed in valence bond theory. In the molecule H2, the hydrogen atoms share the two electrons via covalent bonding. Covalency is greatest between atoms of similar electronegativities. Thus, covalent bonding does not necessarily require the two atoms be of the same elements, only that they be of comparable electronegativity. Because covalent bonding entails sharing of electrons, it is necessarily delocalized. Furthermore, in contrast to electrostatic interactions ("ionic bonds") the strength of covalent bond depends on the angular relation between atoms in polyatomic molecules. The main types of bonds are single, double, triple, and quadruple

Answer 2

Network solids like diamond.

Polar bonds like H20 (water)

Non-polar bonds like any diatomic bond (C2, O2, N2, etc.)

Coordinate covalent bonds where 1 atom supplies both electrons in a pair.

The 5th type is the most simplest one, but I just cannot remember it, sorry.

Answer 3

Polar: Where there is an uneven sharing of electrons, causing the charge to be distributed unevenly, such as in water Nonpolar: Where there is an even sharing of electrons, such as in hydrogen gas Dative: Where both electrons come from the same atom, often encountered in coordination chemistry (well, sort of. there's a better explanation, but this one is still popular) You encounter a dative bond in carbon monoxide. Carbon has 4 electrons, oxygen has 6. They form two regular covalent bonds, and oxygen forms a third bond using two of its free electrons. Each atom has two electrons not participating in a bond, and six electrons participate in the bond.

Answer 4

• Covalent bond -- can be single, double, or triple. The more the bonds the stronger the hold.
• Ionic bonds -- gives up or takes 1 electron.
• Hydrogen bonds -- When water molecules attract each other.
• Van der Waals -- Weak bonds; slight attraction.

Answer 5

Polar: Which happens when an atom needs an electron more than the other atom, and therefore the atom that it's in more need of an electron has more electronegativity, so it's partially negative, and the atom that doesn't have that much of a need for that particular atom is partially positive.

Non-Polar: When atoms shares electron equally. For example, Na and Na, they both want the same quantity of electron therefore they share equally.

Answer 6

non-polar covalent bonds: electrons are shared equally between the atoms.

polar covalent bonds: electrons are shared unequally between the atoms.

Answer 7

polar and nonpolar

Answer 8

ionic, polar covalent, nonpolar covalent
