Question

Which of the following bonds rely on the attraction of positive and negative charges?

A hydrogen bonds
B ionic bonds and hydrogen bonds
C ionic bonds
D covalent bonds
E ionic bonds and covalent bonds

Answer 1

Answer: The bonds that rely on the attraction of positive and negative charges are ionic and Hydrogen bonds. Option B

Explanation: chemical bonds are attraction which exists between atoms and molecules that leads to the formation of chemical compounds. Examples of chemical bonds includes:

- Ionic bonding: this is a type of chemical bonding that involves attraction between a positively charged ion and a negatively charged ion, this occurs in order to obtain a full valence shell for both atoms.

- Hydrogen bond: there is donor and acceptor atoms which constitute the bond. It is primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group,the hydrogen bond donor (Dn) and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac).

- covalent bond: this type of chemical bonding requires sharing of electrons. It doesn't involve attraction of positive and negative charges.

Answer 2

Ionic bonds and hydrogen bonds rely on the attraction of positive and negative charges.

Ionic bond is the force of attraction between oppositely charged ions in a chemical compound. It involves the transfer of electrons from a metal to a non-metal.  Example of an ionic bond sodium fluoride (NaF), sodium chloride (NaCl).

Hydrogen bond is the electrostatic force of attraction between a hydrogen atom attached to a highly electronegative atom. Example is water.
