why tertiary hydrogen is more reactive than secondary or primary

Dear student,

The single tertiary hydrogen "b" is nearly as susceptible as the six, primary "a" hydrogens, and almost doubly susceptible as any of the three, also-primary "d" hydrogens, illustrating the radical stability differences between tertiary and primary hydrogens.

To determine why a third dergree hydrogen is reactive we remove it.
A third degree hydrogen or tertiary hydrogen when removed will give us a tertiary carbocation.
A second degree hydrogen when removed will give us a seconday carbocation.
A first degree hydrogen or primary hydrogen when removed will give us a primary carbocation.
And a tertiary carbocation is favoured more as it is more stable than a secondary carbocation or a first degree carbocation thus, Third degree hydrogens are most reactive.
