WebJust like in the R and S configuration, when there is a tie, you need to look at the atoms connected to the ones being compared. The carbon on the top (isopropyl group) is connected to two carbons and one hydrogen. The carbon on the bottom (ethyl group) is connected to a carbon and two hydrogens. Therefore, isospory gets the higher priority.
