Which of the following is a false statement about a covalent bond?

Which of the following is a flase statement about a covalent bond?





a. It is a force of attraction between a negative and a positive ion.


b. It is a force of attraction between a negative and a positive charge


c. no electrons are transferred from one atom to another.


d. The shared electrons are considered to be attracted by the nuclei of both bonded atoms.


e. It involves sharing of electron pairs.Which of the following is a false statement about a covalent bond?
a is false because covalent bonds are formed when electrons are shared. Ionic bonds are attractions between ions.Which of the following is a false statement about a covalent bond?
Your answer is a. A covalent bond is between 2 non-metals. These are both negative ions. They share the electrons and there is no transfer from 1 atom to another. Some covalent bonds can be called polar-covalent where the more electronegative atom will have a partial negative charge and the less electronegative atom will have a partial positive charge. Therefore, your answer is a. Hope this helps. Good luck.
