Assertion :p-Nitrophenol is a stronger acid than o-nitrophenol. Reason: Intramolecular hydrogen bonding makes the o-isomer weaker than the p-isomer
Assertion (A) o-nitrophenol is less soluble in water than the m- and p-isomers. Reason (R) m and p-nitrophenols exist as associated molecules. (a) Assertion and reason both are correct and reason is correct explanation of assertion. (b) Assertion and reason both are wrong statements. (c) Assertion is correct statement but reason is wrong statement. (d) Assertion is wrong statement but reason is correct statement. (e) Both assertion and reason are correct statements but reason is not correct explanation of assertion.
Assertion (A) Ethanol is a weaker acid than phenol. Reason (R) Sodium ethoxide may be prepared by the reaction of ethanol with aqueous NaOH. (a) Assertion and reason both are correct and reason is correct explanation of assertion. (b) Assertion and reason both are wrong statements. (c) Assertion is correct statement but reason is wrong statement. (d) Assertion is wrong statement but reason is correct statement. (e) Both assertion and reason are correct statements but reason is not correct explanation of assertion.
Assertion (A) p-nitrophenol is more acidic than phenol. Reason (R) Nitro group helps in the stabilisation of the phenoxide ion by dispersal of negative charge due to resonance. (a) Assertion and reason both are correct and reason is correct explanation of assertion. (b) Assertion and reason both are wrong statements. (c) Assertion is correct statement but reason is wrong statement. (d) Assertion is wrong statement but reason is correct statement. (e) Both assertion and reason are correct statements but reason is not correct explanation of assertion.
