Simple Molecules And Covalent Bonds

Question 1

Define covalent bond

Answer 1

Sharing of a pair of electrons between two non metal atoms
No electrons are transferred and no ions are formed. Electrons are only shared by overlapping of energy shells

Question 2

Define molecule

Answer 2

Group of two or more atoms that are held together by covalent bonds

Question 3

Describe the bond strength of covalent bonds

Answer 3

Triple > Double > Single

Question 4

Describe the length of covalent bonds

Answer 4

Triple < Double < Single

Question 5

Name the properties of simple molecular covalently bonded substances.

Answer 5

Weak intermolecular forces (IMF) between molecules
Called Van der Waal’s Forces
Low melting and boiling points
Volatile (turn into gas easily)
Cannot conduct electricity
