Question

How many isomers $x$ of $C_8{H}_{10}$ when react with hot alkaline $KMn{O}_4$ only aromatic dicarboxylic acid ? How many isomers $y$ of $C_4{H}_8$ when reacts with hot alkaline $KMn{O}_4$ give carbondioxide?
Sum of $x+y=?$

Answer 1

$C_4{H}_8$

degree of consaturation $=1$

the $C-C-C=C$

$C-C=C$ $y=2$

$|$

$C$

$C_8{H}_{10}$ degree of consaturation $=4$

$x=3$

So $x+y=5$
