The number of double bonds is two (even number) ∴ Number of G.I. =2n-1+2(n-2) / 2=21+20= 2+1=3 When n is the number of double bonds

Terminal groups are same. The number of double bonds is two (even number)
$∴$ Number of G.I. $= 2^{n - 1} + 2^{(n - 2) /2} = 2^{1} + 2^{0} =$ $2 + 1 = 3$
When $n$ is the number of double bonds
