Question

1. Draw the structural drawing of each requested solvent. Assume kerosene has 13 carbons (in reality it is a mixture of many hydrocarbons.) If a solvent has both a polar section and a non-polar section, circle the polar section and put a rectangle around the non-polar section of the drawing. -U-H44 a. water b. ethanol (CH CHOH) H C- c. 1-butanol (CH3CHCHCHOH) -t-c-f-t d. 1-hexanol (CH CHCHCH,CHCHOH) e. kerosene (hydrocarbon with 10 to 16 carbons) 2. List the solvents in order of increasing polarity and explain your reasoning 201

Explanation / Answer

Order of increasing polarity:

Kerosene < 1- hexanol < 1- butanol < ethanol < water

As no of aliphatic chain increases polarity decreases because aliphatic chains are hydrophobic and hence non polar.
