Question
Chapter 14, Problem 14.62E
Interpretation Introduction
Interpretation:
An explanation regarding the quick evaporation of fingernail polish remover when it is used on nails is to be stated.
Concept introduction:
Acetone is a polar molecule due to the presence of an electronegative oxygen atom that tends to attract the electrons in the double bond closer to itself as compared to the carbon atom. The oxygen acquires a partial negative charge and creates a partial positive charge on carbon atom.
