Concept explainers
a) H3C-Cl
Interpretation:
Using δ+/δ- convention, the direction of expected polarity for C-Cl bond in H3C-Cl is to be indicated.
Concept introduction:
Normally a crossed arrow is used to indicate the direction of the bond polarity. By convention electrons are displaced in the direction of the arrow. The tail of the arrow which looks like a plus sign is electron-poor (δ+) and the head of the arrow is electron rich (δ-).
