(a)
Interpretation:
The Lewis structure of H2O needs to be determined.
Concept introduction:
Lewis structures are also known as Lewis dot structures or electron dot structures. These provide a simplified representation of the valence shell electrons in a molecule. The covalent bonding of a molecule or ion is represented using simple representation as dots. The sharing of electrons is done to get a stable octet structure. These shared electrons are represented as dots and this represents each atom to have eight electrons. The connectivity between the atoms within a molecule is easily represented via a Lewis structure. It is the valence electrons that are represented along with the lone pairs that can also be indicated and identified in the molecule structure.
(b)
Interpretation:
The Lewis structure of CH3NH2 needs to be drawn.
Concept introduction:
A Lewis dot structure is to represent valence shell electrons in a simplified manner. The dots represented here indicate the covalent bonds. These dots also indicate the electrons of individual atoms that are shared. These dots are mostly the valence electrons of the atom. It represents lone pairs as well. The dots between the two atoms represent the bond and dots present on the atom represent a lone pair of electrons.
(c)
Interpretation:
The Lewis structure of ONO- needs to be determined.
Concept introduction:
A Lewis dot structure is to represent valence shell electrons in a simplified manner. The dots represented here is to indicate the covalent bonds. The dots indicate the electrons of individual atoms that are shared. These dots are mostly the valence electrons of the atom. It represents lone pairs as well. The dots between the two atoms represent the bond and dots present on the atom represents a lone pair of electrons.
(d)
Interpretation:
The Lewis structure of SCN- needs to be determined.
Concept introduction:
A Lewis dot structure is to represent valence shell electrons in a simplified manner. The dots represented here is to indicate the covalent bonds.
