That means that the two higher priority groups are on opposite sides of the double bond, and so this is an (E)- isomer - NOT a (Z)-. Nevyžaduje tisk … The second isomer obviously still has the same atoms at each end, but this time the higher priority atoms are on opposite sides of the double bond. $\mathrm{e}^z$ and $\mathrm{e}^z$ have essential singularities at $0$, but $\mathrm{e}^z - \mathrm{e}^z = 0$ does not. The first atom in each list is an H in the CH3 group and a C in the CH3CH2 group. What is attached directly to the carbon-carbon double bond? EZ-ON Products, LLC. For example, could you name these two isomers using cis and trans? Anything beyond that is irrelevant. Concentrate on the atom directly attached to the double bond - in this case the carbon in the CH3 group. Vitamin E has always been known for its myriads of health and beauty benefits. The E- and Z- style is more reliable and particularly suited to tri- or tetra-substituted alkenes, and especially when the substituents are not alkyl groups.
