Answer:
Answer is 4
Explanation:
Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. ... If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.
Covalent bonding can be defined as the sharing of electrons between two atoms.
The statement which best explains the difference between polar and nonpolar covalent bonds is "Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally"
We have:
- Polar covalent bond is a chemical bond in which electrons are shared unequally or unevenly between two atoms.
- Non-polar covalent bond is a chemical bond in which electrons are shared evenly or equally between two atoms.
Therefore, the statement which best explains the difference between polar and nonpolar covalent bonds is "Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally"
