Question

X,Y,Z have same molecular formula `(C_(3)H_(4))` but X,Y,Z have different IUPAC name. If X is cyclic alkene and Y is alkyne then what is true about Z.
A. Z is cyclic alkene
B. Z is alkyne
C. Z is `CH_(2) = C = CH_(2)`
D. All of these

Answer 1

Correct Answer - C
Z can not be cyclic and alkyne
So Z is `CH_(2)=C=CH_(2)` `O(g)rarrO^(2-)(g), underset(therefore "size"uarr)underset("Zeff"darr)"as no. of electron"uarr`
