Which carbocation is the most stable?
C6H5CH2+NO2
Or
C6H5CH2+OCH3
(Note: CH2 is in the upper para position of the benzene ring and NO2 is in the lower para position respectively. Same applies to the second option, OCH3)
Please explain with a proper reason.

Hey dear...
paramethoxybenyl carbocation will be very stabe as the CH3O group or methoxy group has very high +R effect that the lonepairs in oxygen is delocalised into the ring making c+ very stable.
Paranitrobenzyl carbocation is very unstable as nitro group has very high -R effect...It delocalises the e-s towards it
