Question

Five different substances are given to you to be dissolved in water. Which substances are most likely to undergo dissolution in water?

lithium iodide, LiI
sodium fluoride, NaF
potassium bromide, KBr
benzene, C6H6
hexane, C6H14

Answer 1

NaF and KBr

Step-by-step explanation:

LiI comprises Li, a small highly polarizing positive ion and I-, a highly polarizable negative ion which tends towards covalent bond formation according to Fajan's rules hence may not be soluble in water. Benzene and hexane are organic substances which aren't soluble I water.
