Question

which become rancid earlier alkene alkyne or alkane​

Answer 1

Answer:

alkenes and alkynes become rancid quickly because they are unsaturated

Answer 2

Rancidity : Alkenes , alkynes or Alkanes

Explanation:

Rancidity

It is referred to oxidation of substance (food item ) when it is exposed to air due to which it starts smelling bad and even the odour becomes foul .

Now , let us discuss about the rancidity in alkenes , alkanes and alkynes .

In alkanes : There is a single bond between C-C atom .

In alkenes : There is a atleast one  double bond between C-C atom .

In alkynes : There is atleast one triple bond between C-C atom .

In alkenes and alkynes , the oxidation occur easily because of unsaturation .

Whereas in alkanes , there is a single bond that makes the alkane less reactive .

The order towards rancidity :

Alkyne > Alkene> alkane
