Identify the chemical formulas, structural formulas and electron dot structures of the following molecules: water, ammonia, carbon dioxide, fluorine, methane, ethane

Answer 1

The chemical formula represents the number of atoms of each element in a given molecule

a) water: $H_{2}O$

b) Ammonia: $NH_{3}$

c) carbondioxide:$CO_{2}$

d) Flourine:$F_{2}$

e) methane: $CH_{4}$

f) ethane: $C_{2}H_{6}$

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.
