Question

what is covalent bond coordinate bond and singlet bond

Answer 1

a) Covalent Bond :- A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. 

b) Co-ordinate Covalent Bond:- A coordinate bond is a
covalent bond between two
atoms where one of the atoms provides both electrons that form the bond .

c) Singlet Bond:- Triplet carbenes have two unpaired electrons. Most carbenes have a nonlinear triplet ground state, except for those with nitrogen, oxygen, or sulfur atoms, and halides directly bonded to the divalent carbon. Carbenes are called singlet or triplet depending on the electronic spins they possess.

Answer 2

$\huge{\underline{\underline{\sf{\pink{Answer}}}}}$

1. A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

2. A coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction. This type of interaction is central to Lewis theory.

3. In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons. That is, the atoms share one pair of electrons where the bond forms. ... Usually, a single bond is a sigma bond. An exception is the bond in diboron, which is a pi bond.
