Answer:
Option D, ketone
Explanation:
Since Jones reagent (CrO3/H2SO4) is a strong oxidizing agent and oxidize the secondary alcohol to ketone.
Example , isopropanol gets oxidized to propanone.
Primary Alcohol gets oxidized to Carboxylic acids.
 
        
             
        
        
        
what is a non-polar molecule? Atoms are made of small particles. When atoms bond together to form molecules. They share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge making the molecule nonpolar. Polar molecules are the complete opposite.
        
                    
             
        
        
        
Answer:
0.954M solution
Explanation:
molarity = moles solute / volume solution in liters
=> molarity = 1.67 moles / 1.750 L soln = 0.954M solution
