why para nitrophenol is more acidic than ortho nitrophenol?

why para nitrophenol is more acidic than ortho nitrophenol?
In both ortho- and para-nitrophenol, there is one more resonance structure. So due to resonance effects both ortho- and para-nitrophenol are more acidic than the meta-nitrophenol. ortho-Nitrophenol phenoxide ion is stabilised by -R and -I effect where both -I and -R effect are maximum.
Which is more acidic para nitrophenol or ortho nitrophenol?
p - nitrophenol m- nitrophenol o - nitrophenol. d. ... Thus, ortho and para - nitrophenols are more acidic than m- nitrophenol is a little less acidic than p - nitrophenol because of intramolecular hydrogen bonding which makes the loss of a proton difficult to remove.

Why is Ortho Nitrophenol more acidic than Ortho phenol?
Ortho nitrophenol is more acidic than ortho -methoxyphenol. This is because the nitro-group is an electron-withdrawing group. The presence of this group in the ortho position in ortho nitro phenol decreases the electron density in the O −H bond. As a result, it is easier to lose a proton.

Why o-nitrophenol is weaker acid than p-nitrophenol?
P - nitrophenol is a stronger acid than o - nitrophenol, due to intramolecular hydrogen bonding so, reason, Intramolecular hydrogen bonding makes o -isomer weaker than p -isomer is also true and explains the assertion.
