Classify the following bonds as ionic, polar covalent, or covalent, and give your reasons: (a) the cc bond in h3cch3, (b) the ki bond in ki, (c) the nb bond in h3nbcl3, (d) the cf bond in cf4.

a) the C-C bond in : covalent

b) the KI bond in KI : ionic

c) NB bond in : polar covalent

d) the CF bond in :  polar covalent

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.

An ionic bond is formed when an element completely transfers its valence electron to another element. This bond is formed between a metal and an non-metal.

a) the C-C bond in : covalent as there is no diffrence in electronegativity

b) the KI bond in KI : ionic as potassium transfers electron to iodine.

c) NB bond in : polar covalent as there is difference in electronegativity

d) the CF bond in :  polar covalent as there is difference in electronegativity
