6.4 Calculation of number of optical isomers
The replacement of one double bond in an allene by a ring does not alter the basic geometry of the system and appropriately substituted compounds exist in optically active forms.
Related compounds in which $s{p^2} - $ carbon is replaced by nitrogen have also been obtained as optical isomers.
