(a)
Interpretation:
The Lewis structure of C2H3N needs to be drawn.
Concept introduction:
In a Lewis structure of molecule, lone pair of electrons are represented by dots around the atom and shared pair of electrons are represented by lines joining the two atoms sharing the electrons. Number of electron pairs shared determines the type of the covalent bond. If two electrons are shared, single covalent bond is formed, if four electrons are shared, double covalent bond is formed and if there are 6 electrons shared between two atoms, the bond formed will be a triple bond.
(b)
Interpretation:
The Lewis structure of HNO3 needs to be drawn.
Concept introduction:
In a Lewis structure of molecule, lone pair of electrons are represented by dots around the atom and shared pair of electrons are represented by lines joining the two atoms sharing the electrons. Number of electron pairs shared determines the type of the covalent bond. If two electrons are shared, single covalent bond is formed, if four electrons are shared, double covalent bond is formed and if there are 6 electrons shared between two atoms, the bond formed will be a triple bond.
(c)
Interpretation:
The Lewis structure of C3H6 needs to be drawn.
Concept introduction:
In a Lewis structure of molecule, lone pair of electrons are represented by dots around the atom and shared pair of electrons are represented by lines joining the two atoms sharing the electrons. Number of electron pairs shared determines the type of the covalent bond. If two electrons are shared, single covalent bond is formed, if four electrons are shared, double covalent bond is formed and if there are 6 electrons shared between two atoms, the bond formed will be a triple bond.
