POLAR AND NONPOLAR MOLECULES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following statement best describe a nonpolar covalent bond?
A
two atoms share a pair of electrons with each other
B
no electrons are shared between atoms
C
1 atom in a molecule has a partial charge bec. of unequal electron sharing
D
one or more elements shared electron
Explanation: 

Detailed explanation-1: -A non-polar covalent bond is a type of chemical bond that is formed when electrons are shared equally between two atoms. Thus, in an atom, the number of electrons shared by the adjacent atoms will be the same. The covalent bond is also termed as nonpolar because the difference in electronegativity is mostly negligible.

Detailed explanation-2: -Explanation: A polar covalent bond describes a bond between two atoms that share electrons unequally. This results from a difference in electronegativity between the atoms.

Detailed explanation-3: -A nonpolar covalent bond is a covalent bond in which the bonding electrons are shared equally between the two atoms. In a nonpolar covalent bond, the distribution of electrical charge is balanced between the two atoms.

Detailed explanation-4: -Covalent bonds involve the equal sharing of an electron pair by two atoms. Examples of important covalent bonds are peptide (amide) and disulfide bonds between amino acids, and C–C, C–O, and C–N bonds within amino acids.
