CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323701 Assertion :
Substituents affect the stability of the conjugate base and acidity of carboxylic acids.
Reason :
Electron withdrawing groups decrease the acidity of carboxylic acids.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

323702 Assertion :
Pure acetic acid is converted into ice like solid called glacial acetic acid.
Reason :
Acetic acid is stronger than \(\mathrm{HCOOH}\).

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323703 In the anion \(\mathrm{HCOO}^{-}\)the two carbon-oxygen bonds are found to be of equal length. What is the reason for it?

1 The anion \(\mathrm{HCOO}^{-}\)has two equivalent resonating structures
2 The anion is obtained by removal of a proton from the acid molecule
3 Electronic orbitals of carbon atom are hybridised
4 The \(\mathrm{C}=\mathrm{O}\) bond is weaker than the \(\mathrm{C}-\mathrm{O}\) bond
