Question

what is covant bond . explain in detail​

Answer 1

Answer:

the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. A covalent bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.

Answer 2

$\mathbb {COVALENT \: \:BOND}$

• A covalent bond is formed by equal sharing of electrons from both the participating atoms.
• The pair of electrons participating in this type of bonding is called shared pair or bonding pair.
• The covalent bonds are also termed as molecular bonds.
• Sharing of bonding pairs will ensure that the atoms achieve stability in their outer shell which is similar to the atoms of noble gases

$\mathfrak{Covalent \: Bonding \: can \: be }$

$\mathfrak{Achieved \: in \: two \: Ways:}$

1. Sharing of electrons between atoms of the same kind E.g. Formation of H2, Cl2, O2, etc.
2. Sharing of electrons between atoms of different kind E.g. Formation of CH4, H2O, NH3, etc.

$\mathbb{Covalent \: Bonding \: In \: \: Carbon}$

As per the electronic configuration of Carbon, it needs to gain or lose 4 electrons to become stable, which seems impossible as:

• Carbon cannot gain 4 electrons to become C4-, because it will be tough for 6 protons to hold 10 electrons and so the atom will become unstable.
• Carbon cannot lose 4 electrons to become C4+ because it would require a large amount of energy to remove out 4 electrons and also the C4+ would have only 2 electrons held by proton, which will again become unstable

Carbon cannot gain or donate electrons, so to complete its nearest noble gas configuration, it shares electron to form a covalent bond.
