Stereoisomerism

Question 1

Stereoisomerism

Answer 1

Have the same structural formula but a different arrangement of atoms in space

Question 2

Why E/Z isomerism occurs in alkenes

Answer 2

No rotation around the C=C double bond

Thus, have to have diff arrangement for isomerism

Question 3

E/Z isomerism

Answer 3

stereoisomerism around the double bond arises as rotation about double bond is restricted
groups attached to each C is fixed relative to each other

Question 4

Conditions for E/Z isomerism

Answer 4

=> a C=C double

=> Diff group attached to each carbon atom of the double atom

Question 5

Cis - Trans (a type of E/Z isomerism) Isomerism

Answer 5

=> a C=C double bond
=> Diff. groups attached to each C atom of the double bond
=> Each C in double bond has a H bonded to it

Question 6

Z isomerism

Answer 6

If the group of higher priority are on the same side of double bond

Question 7

E isomerism

Answer 7

If groups of higher priority are diagonal

Question 8

E

Answer 8

Entengen = Opposite

REMEMBER Epposite

Question 9

Z

Answer 9

Zusamen = Same side

REMEMBER Zame Zide

Question 10

Assigning Priority

Answer 10

The higher the atomic (proton) number of what’s bonded to the double bonded C
=> the higher the priority
