Answer 3

A student investigated the reaction of different vegetable oils with hydrogen. 100 cm3 of hydrogen
was passed through 1 g samples of vegetable oils containing a suitable catalyst.
The volume of hydrogen remaining after each reaction was recorded.
vegetable oil
volume of hydrogen
remaining / cm3
P 100
Q 87
R 63
S 0
Which vegetable oils are unsaturated?
A P only
B Q and R only
C Q, R and S only
D S only
