I know that meta position shown no resonance effect and hyperconjugation effect . So According to the order given I guess Hyperconjugating effect is taken into account as -CH3 has no Resonance effects.
But are the hydrogen in methyl group alpha hydrogens ? As per I know that hyperconjugation is only shown if alpha hydrogen is present .
I am not getting the order . If only inductive effect was considered the order should have been 1>2>3 but its 1>3>2 please explain this order to me .
