Are covalent bonds the strongest?
Generally, ionic bonds are much stronger than covalent bonds. In ionic bonds, there is complete transfer of electrons between elements to form a stable compound. While in covalent bond, there is only sharing of electrons between two elements to form a stable compound.
The strongest bond is the Covalent Bond. There are a number of ways in which atoms bond with each other. The strongest form of covalent bond, in which the atomic orbitals overlap directly between the nuclei of two atoms, is a sigma bond.
Intramolecular covalent bonding is the most difficult to break. These ties are perhaps the toughest to break and yet the most stable.
Triple bonds are the shortest and the strongest bonds (since the atoms are closer together, more difficult to separate from each other, would take more energy to break the bond), and single bonds are the longest and weakest bonds (is easier to separate atoms that are farther apart from each other).

Molecular covalent structures
The atoms in molecular covalent molecules are held together by strong covalent bonds. Although these bonds are strong, there are only weak forces of attraction between molecules. These weak attractive forces are called van der Waals' forces and can be broken with little energy.
Covalent and ionic bonds are both typically considered strong bonds. However, other kinds of more temporary bonds can also form between atoms or molecules. Two types of weak bonds often seen in biology are hydrogen bonds and London dispersion forces.
In chemistry, a covalent bond is the strongest bond, In such bonding, each of two atoms shares electrons that bind them together. For example - water molecules are bonded together where both hydrogen atoms and oxygen atoms share electrons to form a covalent bond.
Therefore, the order of strength of bonds from the strongest to weakest is; Ionic bond > Covalent bond > Hydrogen bond > Van der Waals interaction.
Ionic bonds are stronger than covalent bonds because the electronegativity difference between the two elements is much greater than that of two elements in a covalent bond. In a covalent bond electrons are shared between the two elements and will often favor one element over the other depending on polarity.
Why are covalent bonds weak?
This is because the atoms within the covalent molecules are very tightly held together. Each molecule is indeed quite separate and the force of attraction between the individual molecules in a covalent compound tends to be weak. We require very little energy in separating the molecules.
Because covalent bonds are weaker than ionic bonds, covalent compounds typically have lower melting points and boiling points. Most covalent compounds are fairly soft and flexible because covalent compounds are not very rigid. Covalent compounds usually don't dissolve in water, unless they are polar compounds.
Covalent Bond Properties
These are considered strong and unbreakable chemical bonds that bind the atoms in place. These will only pair the electrons and do not form new ones. After covalent bonds are formed, it is almost impossible to break them.
So, we can say that covalent bonds are stable. Also we know that bond energy is approximately 83 kcal/mol which clearly indicates the high bond strength of covalent bonds. Hence we can say that covalent bonds cannot be easily broken.
The hydrogen bond is the weakest bond among the covalent, ionic, and metallic bonds. A hydrogen bond occurs as a weak attraction between the molecules because it depends on a temporary imbalance in electron distribution.
Covalent compounds generally have low boiling and melting points, and are found in all three physical states at room temperature.
Five examples of covalent bonds are hydrogen (H₂), oxygen (O₂), nitrogen (N₂), water (H₂O), and methane(CH₄). 2. What is a covalent bond? A chemical bond involving the sharing of electron pairs between atoms is known as a covalent bond.
As polar and nonpolar both bonds are covalent so it is difficult to predict which one is stronger. In the polar bond some extra force of attraction is there so the polar bond is stronger than nonpolar bond.
The four valence electrons of each carbon atom participate in the formation of very strong covalent bonds. These bonds have the same strength in all directions. This gives diamonds their great hardness. Since there are no free electrons to wander through the structure, diamonds are excellent insulators.
We measure the strength of a covalent bond by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy. The stronger a bond, the greater the energy required to break it.
Do covalent bonds have strong forces?
However, although the covalent bonds holding the atoms together in a simple molecule are strong, the intermolecular forces between simple molecules are weak.
Stable molecules exist because covalent bonds hold the atoms together. We measure the strength of a covalent bond by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy (see Figure 1).
Atoms in simple molecules are held together by covalent bonds which are very strong, which take a lot of energy to break. The molecules themselves are held together by weak intermolecular forces, called van der waals forces.
Covalent Bonds are stronger than hydrogen bonds because a covalent bond is an attraction within molecules whereas hydrogen bonds are attractions between molecules and are therefore generally weaker.
Ionic bonds are the strongest type of bond. However, a covalent bond is stronger than an ionic bond in certain scenarios. Only covalent bonds can have different numbers of bonds. A triple bond is stronger than a double bond which is stronger than a single covalent bond.
