Activity 1.3 of
Draw the Lewis structure of carbon (Z = 6) and hydrogen (Z = 1) atoms. How many
valence electrons are there in an atom of carbon and hydrogen respectively?
Consider three organic compounds containing two carbon atoms each. The two
carbon atoms contributed one electron each in the first, two electrons each in the
second and three electrons each in the third for the bond they form between them
by sharing the electrons. The remaining valence electrons of each carbon atom in all
the three compounds were used to form bonds with hydrogen atoms.
What type of covalent bond do the two-carbon atoms form between themselves
in the first, the second and the third compound, respectively?
How many hydrogen atoms can form bonds with each carbon atom in the first, the
second and the third compound, respectively?
Draw line or dot formula to show the formation of the bonds between the carbon
atoms and carbon and the hydrogen atoms in the first, the second and the third
compound, respectively.
d If the three compounds mentioned above are hydrocarbons, define
hydrocarbons?
f If the first compound is a saturated hydrocarbon, the second and the third unsaturated what is the basis for such a classification of hydrocarbons ​
