Concept explainers
(a)
Interpretation:
The bonds in C-O and C-N should be labeled with δ+ and δ- to show the direction of polarity.
Concept Introduction:
The symbol δ+ is given to the less electronegative atom and the symbol δ- is given to the more electronegative atom. In bonding between atoms of different electronegativity, electrons are pulled away from less electronegative element towards the higher electronegative element.
(b)
Interpretation:
The bonds in C-F and C-Cl should be labeled with d+ and d- to show the direction of polarity.
Concept Introduction:
The symbol d+ is given to the less electronegative atom and the symbol d- is given to the more electronegative atom. In bonding between atoms of different electronegativity, electrons are pulled away from less electronegative element towards the higher electronegative element.
(c)
Interpretation:
The bonds in Si-C and P-H should be labeled with δ+ and δ- to show the direction of polarity.
Concept Introduction:
The symbol δ+ is given to the less electronegative atom and the symbol δ- is given to the more electronegative atom. In bonding between atoms of different electronegativity, electrons are pulled away from less electronegative element towards the higher electronegative element.
