The chemical formula represents the number of atoms of each element in a given molecule
a) water: [tex]H_{2}O[/tex]
b) Ammonia: [tex]NH_{3}[/tex]
c) carbondioxide:[tex]CO_{2}[/tex]
d) Flourine:[tex]F_{2}[/tex]
e) methane: [tex]CH_{4}[/tex]
f) ethane: [tex]C_{2}H_{6}[/tex]
Structural formula is based on hybridization:
a) water: sp3 hybridized (two lone pair of electrons on central oxygen atom) shape "Bent"
b) Ammonia: sp3 hybridized (one lone pair of electrons on central oxygen atom) shape "pyramidal"
c) carbondioxide: linear
d) Flourine: linear
e) methane: sp3 hybridized , shape : tetrahedral
f) ethane: sp3 hybridized,sp3 hybridized (two lone pair of electrons on central oxygen atom) shape "Bent"
The structural formula and electron dot structures are shown in the figure.
