What if you working with a diene how do differentiate e and z
@Leah4sci
@Leah4sci 2 месяца назад
The process would be the same. You would just need to identify the E/Z configuration for both double bonds in the molecule and include both in the structure's name. If you haven't already, make sure to view my full tutorial on Geometric Isomers at Leah4sci.com/CisTrans

what do u mean by atomic number? is that size?
@Leah4sci
@Leah4sci Год назад
The atomic number is the number of protons in an atom. It's the large number notated in each box of the periodic table of elements. It's not directly proportional to the atomic radius/size.
