Question

Now, let, the degree of unsaturation of B = $x$
The degree of unsaturation of C = $y$
Total number of stereoisomers of B = $z$
Total number of stereoisomers of C = $m$
Then, calculate the value of $\frac{(xy+1)}{m+z}$

Answer 1

(9BBN = 9- Borabicyclo [3.3.1] nonane.)


There are no stereoisomers in B and 2 stereoisomers in case of C due to one stereo centre.
So, $x=2,y=2,z=0,m=2$
So, $\frac{xy+1}{(m+z)}=\frac{5}{2}=2.5$
