Lewis structure

Lewis structure, also known as Lewis dot diagram is defined as the structural representation of a molecule where dots are used to show electron positions around the atoms and lines (or dot pairs), and gives the covalent bond between atoms. Each dot in a Lewis diagram represents a valence electron and one bond is represented as two electrons. The sum of all atoms of each element present in a molecule is shown by molecular formulas.

Lewis structures of the given line-angle structures

a) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains five carbon atoms, eleven hydrogen atoms, and only one nitrogen atom. Hence, the molecular formula of the compound will be C₅H₁₁N .

b) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains eight carbon atoms, sixteen hydrogen atoms, and only one oxygen atom. Hence, the molecular formula of the compound will be C₈H₁₆O

c) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains four carbon atoms, five hydrogen atoms, and only one nitrogen atom. Hence, the molecular formula of the compound will be C₄H₅N .

d) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains five carbon atoms, ten hydrogen atoms, and only one oxygen atom. Hence, the molecular formula of the compound will be C₅H₁₀O

e) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains seven carbon atoms, ten hydrogen atoms, and only one oxygen atom. Hence, the molecular formula of the compound will be C₇H₁₀O

f) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains six carbon atoms, eight hydrogen atoms, and only one oxygen atom. Hence, the molecular formula of the compound will be C₆H₈O

g) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains eight carbon atoms, eight hydrogen atoms, and only one oxygen atom. Hence, the molecular formula of the compound will be C₈H₈O.

h) Lewis structure from the given line-angle structure can be represented by the figure as shown below:

Lewis structure

From the Lewis structure, it can be seen that the compound contains four carbon atoms, eight hydrogen atoms, and only one oxygen atom. Hence, the molecular formula of the compound will be C₄H₈O
