what are the different types of bonds and explain each type with its example
Answers
Answer:
Hello bro
Explanation:
Chemical bonds are forces that hold atoms together to make compounds or molecules.
Chemical bonds include covalent, polar covalent, and ionic bonds.
Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.
Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other. This attraction is known as an ionic bond.
Key Terms
bond: A link or force between neighboring atoms in a molecule or compound.
ionic bond: An attraction between two ions used to create an ionic compound. This attraction usually forms between a metal and a non-metal.
covalent bond: An interaction between two atoms, which involves the sharing of one or more electrons to help each atom satisfy the octet rule. This interaction typically forms between two non-metals.
intramolecular: Refers to interactions within a molecule.
intermolecular forces: Refers to interactions between two or more molecules.
Chemical bonds
Chemical bonds are the connections between atoms in a molecule. These bonds include both strong intramolecular interactions, such as covalent and ionic bonds. They are related to weaker intermolecular forces, such as dipole-dipole interactions, the London dispersion forces, and hydrogen bonding. The weaker forces will be discussed in a later concept.

Chemical bonds: This pictures shows examples of chemical bonding using Lewis dot notation. Hydrogen and carbon are not bonded, while in water there is a single bond between each hydrogen and oxygen. Bonds, especially covalent bonds, are often represented as lines between bonded atoms. Acetylene has a triple bond, a special type of covalent bond that will be discussed later.
Covalent Bonds
Chemical bonds are the forces of attraction that tie atoms together. Bonds are formed when valence electrons, the electrons in the outermost electronic “shell” of an atom, interact. The nature of the interaction between the atoms depends on their relative electronegativity. Atoms with equal or similar electronegativity form covalent bonds, in which the valence electron density is shared between the two atoms. The electron density resides between the atoms and is attracted to both nuclei. This type of bond forms most frequently between two non- metals.
When there is a greater electronegativity difference than between covalently bonded atoms, the pair of atoms usually forms a polar covalent bond. The electrons are still shared between the atoms, but the electrons are not equally attracted to both elements. As a result, the electrons tend to be found near one particular atom most of the time. Again, polar covalent bonds tend to occur between non-metals.

Answer:
Different types of bonds are electrovalent bond, covalent bond, and coordinate bond.
Examples of electrovalent Bond : NaCl KCL MgCl2 cable, examples of covalent bond
H2 N2 O2 F2. Examples of co-ordinate Bond, when ammonia is added to hydrochloric acid.
