Question

why alkanes so inert

Answer 1

Alkanes are generally unreactive. Alkanes contain only C–H and C–C bonds, which are relatively strong and difficult to break. The similar electronegativities of carbon and hydrogen give molecules which are non-polar

Answer 2

Heya,

Alkanes are so inert they have only sigma bond in them.And sigma bonds are the strongest out of the other covalent bonds.
