Looking at the answer choices, we can see that all of the answers have nonmetals, and therefore all have covalent bonds. This is a nonpolar covalent bond. A nonpolar covalent bond. Figure \(\PageIndex{1}\) Polar versus Nonpolar Covalent Bonds. A covalent 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. Figure \(\PageIndex{1}\) Polar versus Nonpolar Covalent Bonds. Answer and Explanation: Covalent bonds are formed between 2 or more nonmetals. (b) The chlorine atom attracts the electrons in the bond more than the hydrogen atom does, leading to an imbalance in the electron distribution. Such polar compounds in solutions produce free ions. When placed on a classification scale, the ionic bond (the bond that exists between a metal and a non-metal) has the most electronegativity and polarity. Atoms that attract an electron more strongly are considered to be more electronegative. This is a nonpolar covalent bond. (a) The electrons in the covalent bond are equally shared by both hydrogen atoms. The chemical bond that occurs between molecules can be of two types, namely, ionic and covalent bonds. The molecule that is composed of the same 2 elements has non polar covalent bonds since if the elements are the same they have the same electronegativities and share electrons in the bond equally. C. A polar covalent bond. Covalent bonds between identical atoms (as in H 2) are nonpolar—i.e., electrically uniform—while those between unlike atoms are polar—i.e., one atom is slightly negatively charged and the other is slightly positively charged. Nonpolar and polar covalent bonds differ on the basis of whether they share electrons equally or unequally. A. O2. A covalent bond that has an equal sharing of electrons (part (a) of Figure \(\PageIndex{1}\)) is called a nonpolar covalent bond. Some atoms are exceptions to the octet rule by having an expanded octet. The compounds having polar covalent bonds undergo ionization when dissolved in any polar solvent, such as water. The O-H bond in water (H 2 O) is also a polar bond – the hydrogen atom has a slight positive charge, and oxygen atom has been the slight negative charge, i.e., H +δ – O-δ. The relative attraction of an atom to an electron is known as its electronegativity. Which type of bond will most likely be found in HBr? Which compound contains only nonpolar covalent bonds? Chemical Bonding: Polar and Nonpolar Covalent Bonds A bond is a chemical affinity between two atoms in which the electrons staying in an atom make a bond between two atoms. Non-polar covalent bonds have no defined axis or axes compared to polar covalent bonds. (a) The electrons in the covalent bond are equally shared by both hydrogen atoms. The ionic bond is followed by the polar covalent bond and, lastly, the non-polar covalent bond.
