Concept explainers
a)
Interpretation: EN difference for each polar bond is to be determined.
Concept introduction: Atom is said to be electronegative if it has a tendency to attract electrons towards itself in a bond. Higher the electronegativity of element more will be attraction of electrons and vice-versa.
b)
Interpretation: Dipole moment arrow for each polar bond should be drawn.
Concept introduction: Dipole moment is a measure of bond polarity in the molecule. It is defined as product of charge and distance of separation between opposite charges. Polar molecules consist of dipole moments due to presence of charges in them whereas non-polar molecules do not have dipole moments. Dipole moment arrow is directed from element of low electronegativity to element of high electronegativity.
c)
Interpretation: Partial positive and partial negative charges on molecules should be determined.
Concept introduction: Atom is said to be electronegative if it has a tendency to attract electrons towards itself in a bond. Higher the electronegativity of element, more will be the attraction of electrons and vice-versa.
d)
Interpretation: Electron cloud for molecules in order to indicate areas of high and low electron density should be determined.
Concept introduction: Atom is said to be electronegative if it has a tendency to attract electrons towards itself in a bond. Higher the electronegativity of element, more will be attraction of electrons and vice-versa.
