Alkanes are inert is nature, why ?

Explanation

Alkanes are quite inert substances with highly stable nature. Their inactiveness has been explained as:
(i) Alkanes have all the `C-C` and `C-H` bons being stronger a bonds and are not influenced by acid, oxidants under ordinary conditions.
(ii) The `C-C` bond is completely non polaar and `C-H` is weak polar. Thus polar species i.e. electrophiles or nucleophiles are unable to attack these bonds under ordinary conditions.
