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
