Question

Which type of bond will most likely be found in HBr?

an ionic bond
a metallic bond
a polar covalent bond
a nonpolar covalent bond

Answer 1

Answer: a polar covalent bond

Step-by-step explanation:

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. Example:
`HBr`

Non polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms. Example:
`N_2`

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example:
`NaCl`

Answer 2

 H and Br are both non-metals which means the bond that comes in between them is covalent. If the composing elements are non-metal and metal, then the bond should be ionic. In this case, HBR is considered polar because the Br atom pulls on the electron much harder than the H atom. Answer is C.
