Question

5 examples for covalent bond

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

examples include,

O2 (oxygen) - two oxygen atoms bonded to form one oxygen molecule

H2 (hydrogen) - two hydrogen atoms bonded to form one hydrogen molecule

SO2 (sulfurdioxide) - one sulfur atom bonded with two oxygen atoms.

H-O bonds (e.g. in water, alcohol hydroxil chemical functional group)

H-N bond (in ammonia, hydrazine…)

N-N triple bond [N:::N] in the N2 molecule

C-C single bond (as in ethane)
