Question

what do the physical and chemical properties of compounds most influenced by? bond polarity atomic mass isotopic character bond length

Explanation:

Bond polarity determines the distribution of charge in a compound, which in turn affects its physical properties like solubility, melting - point, boiling - point, and chemical reactivity. Atomic mass mainly affects physical properties like density but has less impact on chemical reactivity compared to bond polarity. Isotopic character mainly affects physical properties related to mass - dependent phenomena and has little impact on most chemical and physical properties of compounds in normal chemical reactions. Bond length affects bond strength and some physical properties but is secondary to bond polarity in influencing overall physical and chemical properties.

Answer:

Bond polarity
