Double and triple bonds
3hexene (with a double bond)
Question 20
 consult tabel IV and VI and find the next data:
 table IV: the interatomic distances of covalent bonding types
 table VI: the bonding energies of covalent bondings
 Copy from this tables the information about the bonds: C  C, C = C, C ≡ C;
 Put those data in a diagramme and make a graph.
The xaxes of this graph shows the three bondings and the yaxes shows the distances as well as the energies.
then you get two different graphs in one scheme.

Look well and draw your conclusions.
 Make an estimation of distance and energy of a C ^{...} C bond in the benzene ring.
Question 21
Is the following statement true?
"In a triple bond, e.g. in acetylene (= ethyne) 2 Catoms share a total of 6 electrons."
Explain your answer.
