1. Which of the following are correctly ranked in order of increasing priority with respect to the assignment of stereochemistry?

Select one:
a. CO2Ph < CO2H < SO3H < NH2 < Cl
b. isopentyl < isobutyl < n-butyl < isopropyl < methyl
c. cyclopropyl < CH3 < SO3H < F < I
d. CHO < CH3 < NO2 < NH2 < Br
e. n-butyl < tert-butyl < COOH < NO2 < Cl

how do i work this out ?

Select one:
a. 1,1-diiodo-2,3-diethylnonane
b. 1,2-diiodo-2,3-diethylnonane
c. 1-iodo-2,3-diethylnonane
d. 1-iodo-2,3-diethylnonene
e. 4-ethyl-3-iodo-3-methyldecane

4. What is the expected major product arising from the reaction of 3-methyloct-3-ene with hydrogen bromide? (Hint; draw out chemical structures)
Select one:
a. 4-bromo-3-methyloctane; via a Markovnikov addition
