No. of Geometrical Isomers

Engineering Entrance , JEE Main , JEE Advanced , Chemistry , Organic Chemistry

1. If a compound contains only 1 d.b. then no. of geometical isomers are 2

2. if a compound contains 2 or more than 2 d.b. and end groups are different , then no. of geometrical isomers will be where n is no. of d.b.

3. If a compound contains 2 or more than 2 d.b. and end groups are same , then no. of geometrical isomers will be where

p =n/2 if d.b. are even and p=(n+1)/2 if d.b. are odd

these formulas have limitations ...as in if there are more than 4 chiral centres these will not work..even for 2 chiral centres it will not work becuase you will have to face the case of psuedo chiral
