cis-but-2-ene reacts with cold dilute acidified potassium manganate(VII) solution to give product X. cis-but-2-ene reacts with hot concentrated acidified potassium manganate(VII) solution to give product Y. Which row describing the reactions of X and Y is correct? [Table 30.1: Reactions of X and Y]
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Awhen sodium metal is added to
separate samples of X and Y
both X and Y will react
when sodium hydroxide solution is
added to separate samples of X and Y
neither X nor Y will react
Bwhen sodium metal is added to
separate samples of X and Y
both X and Y will react
when sodium hydroxide solution is
added to separate samples of X and Y
only one of X and Y will react
Cwhen sodium metal is added to
separate samples of X and Y
only one of X and Y will react
when sodium hydroxide solution is
added to separate samples of X and Y
neither X nor Y will react
Dwhen sodium metal is added to
separate samples of X and Y
only one of X and Y will react
when sodium hydroxide solution is
added to separate samples of X and Y
only one of X and Y will react
✓ Correct answer
B: when sodium metal is added to separate samples of X and Y both X and Y will react when sodium hydroxide solution is added to separate samples of X and Y only one of X and Y will react
