2a. A solution of acidified KMnO4 was reacted with three hydrocarbons X, Y, and Z.
Both X and Z decolourized the KMnO4 solution while Y did not, X reacted with
ammoniacal solution of silver trioxonitrate (v) while Z did not.
i. Name the homologues series to which X, Y and Z belongs.
ii. Write the General Molecular Formula of Z.
iii. Draw the structure of the third member of the homologous series of X.
iv State two(2) physical properties of Y.
