Answer:

CH3, H, NO2, OCH3, F

Step-by-step explanation:

Alkyl groups have a +I (electrons donation) inductive effect hence they push electrons towards the carbocation centre thereby stabilizing it. On the other hand, with increasing electronegativity and -I (electron withdrawing) inductive effect, the carbocation becomes destabilized. The greatest being F which is very electronegative.
