Q.
The total number of acylic isomers including the stereoisomers (geometrical and optical), with the molecular formula $ C_{4}H_{7}Cl $ is
Uttarkhand PMTUttarkhand PMT 2008
Solution:
Degree of unsaturation $=\frac{\left(2 n_{c+2}\right)-\left(h_{H}+n_{x}\right)}{2}$
$=\frac{(2 \times 4+2)-(7+1)}{2}=1^{\circ}$
$ D.U =1^{0} $
here, $C =$ carbon atoms
$H =$ hydrogen atoms
$X =$ halogen atoms
$1^{\circ} DU$ suggest that (on pound either contain one $( C = C )$ bond or cyclic ring. Since acrylic isomers have been a sked in problem, the number of acrylic isomers in during
stereoisomers of $C _{4} H _{7} Cl$ is:
