In a polar bond, where does the δ+ symbol typically indicate?

• A. The electronegative atom
• B. The electropositive atom
• C. The middle atom in a group
• D. The atom with the least number of electrons

Answer: (B)

In a polar bond, the δ+ symbol indicates the electropositive atom. This representation is used to denote a partial positive charge, which arises when two different atoms form a bond and share electrons unequally due to differences in their electronegativities. The atom that attracts the electron density more strongly (the more electronegative atom) gains a partial negative charge (δ-), while the atom that is less electronegative has a partial positive charge (δ+). This concept is crucial in understanding the polarity of molecules, as it impacts their physical and chemical properties, including solubility and reactivity. The electropositive atom typically possesses a weaker attraction for the bonding electrons, leading to a buildup of positive character and the notation of δ+.
