Main question to be answered: what is the polarity and solubility of structure 1 and structure 2?
Log P (means): A negative value for logP means the compound has a higher affinity for the aqueous phase (it is more
hydrophilic); when logP = 0 the compound is equally partitioned between the lipid and aqueous phases; a positive value
for logP denotes a higher concentration in the lipid phase (i.e., the compound is more lipophilic)
STRUCTURE 1: Count Starting from the Left

PROBLEM
An unknown compound was discovered by a group of scientists. It was large with different
functional groups. The scientists decided to divide the molecules into significant parts by
reacting it with different reagents. Using analytical instruments, the smaller parts were
identified:
1. methyl
2. a hydrocarbon chain of 10 carbons with two double bonds and a triple bond
3. ethyl
4. propyl
The methyl, ethyl and propyl groups are found to have 2:2:1 mass ratio respectively per
molecule of the longest hydrocarbon. You are tasked to suggest possible structures of the
unknown compound by combining all the groups mentioned above. Plus, you are to explain
possible properties like polarity, solubility, melting points, and boiling points. You are to
produce drawings of the structures and a summary of their properties which you compared.
Your output will be evaluated according to the rubric below.
Here are the things that you are expected to complete: (QUESTIONS)
1. Give 2 possible structures of the unknown compound with proper name and classification.
2. Compare their properties: polarity, solubility, melting points, and boiling points.
3. If these were halogenated with 2 Cl each, what will be the possible structures and names?
