Concept explainers
(a)
Interpretation:
The bonds in Si-O and Si-S 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 H-F and H-Br 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.
(c)
Interpretation:
The bonds in C-B and C-Li 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.

(a) CN (b) NO (c) CClarrow_forwardLabel each of the following bonds as ionic (I), polar covalent (PC), or nonpolar covalent (NC). N-S C-H C-Oarrow_forwardFor each bond, show the direction of polarity by selecting the correct partial charges.arrow_forward
- Draw Lewis structures for each of the following molecules: (a) CH5N (contains a bond between C and N); (b) CH3NO2 (contains a bond between C and N but no bonds between C and O); (c) CH2O; (d) CH2Cl2; (e) BrCNarrow_forwardRank in order of increasing polarity. C-F, C-N, N-F, C-Harrow_forwardOrganize the following bonds from least polar to most polar. Label most polar and least polar. C-F, C-H, C-Cl, C-B, and C-Carrow_forward
