Question

The ____________ bonds in bromine, Br2, allows for complete dissolving but not dissociation cyclohexane. Bromine will not dissolve or dissociate in water.
A) ionic B) metallic C) polar covalent D) nonpolar covalent

Answer 1

Answer: non polar covalent

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. Example: $NaCl$

Metallic bond is the bond formed between the nucleus of metal and the free electrons. Example: $Na$

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

A non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.Example: $Br_2$

Water being polar only dissolves polar substances in it and hence bromine cannot dissolve in water.

Answer 2

The answer would be non-polar covalent.
Bromine is a non-metal, making the bond covalent.
The bond is non-polar because there is no unequal sharing between electrons because both elements in the bond are the same; they have the sane electro negativities.
