describe in brief the types of covalent bond
Answers
Answer:
Explanation:
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: There three type of covalent bonds :
Single covalent bond , Double covalent bond and Triple covalent bond
Explanation:
There are three type of covalent bond:
Single covalent bond : A single covalent bond is formed when only one pair of is shared between the atoms. It is represented by one dash (-) and it is weker than double and triple covalent bond. example , H-H , F-H
Double covalent bond : A double covalent bond is formed when two pairs of electrons are shared between the atoms.It is represnted by two dash (=) and it stronger than single and weaker than triple covalent bond. example O2 , CO2
Triple covalent bond : A triple covalent bond is formed by by the sharing of three pairs of electrons between the atoms.It is represented by three dashes where it the strongest covalent bonds . example N2 ,CO
