Question

You are a forensic scientist and have been asked to identify a white, unlabeled powder recovered from the scene of a crime. As a first step, you're interested in learning if the compound is polar or non-polar. What should you do and how should you interpret your findings?

Answer 1

Answer and Explanation:

What one can do is to try dissolving the  powder in $H_{2}O$; if the powder fails to get dissolved, then we can state that it is a non polar compound.  Non-polar compounds are known as or referred to as the compounds which tends to not have the slightly positive and negative charges within the given compound. Electronegativity differences of these  compounds are mostly in between 0 and 0.2.
