Direction: In the following questions (QUESTIONS 49-53), a statement of ASSERTION is followed by a statement of
REASON. Evaluate both statements. Then chose the answers from the options below.
A - Assertion and reason both are correct statements and reason is the correct explanation for assertion.
B-Assertion and reason both are correct statements but reason is not the correct explanation for assertion.
C-Assertion is a correct statement but reason is a wrong statement.
D-Assertion is a wrong statement but reason is a correct statement.
49. ASSERTION: Lower aldehydes and ketones are soluble in water but the solubility decreases as molecular mass
increases.
REASON: Aldehydes and ketones can be distinguished by Tollen's reagent.
50. ASSERTION: Aldehydes are more reactive than ketones.
REASON: The carbonyl group in aldehydes is more electrophilic than that in ketones.
51. ASSERTION: Alkyl aldehydes are less reactive than aromatic aldehydes, such as benzaldehyde.
REASON: The aromatic ring allows electron delocalization via a resonance effect that also reduces the positive charge
on the carbonyl carbon.
52. ASSERTION: The addition of 1 mole of alcohol to an aldehyde gives a hemiacetal, and to a ketone a hemiketal
REASON: Formation of hemiacetals is usually catalyzed by acids, but also may be achieved in the presence of base.
53. ASSERTION: Acetylene on treatment with alkaline KMnO4 produce acetaldehyde.
REASON: Alkaline KMnO4 is a reducing agent.
54. Why is ethanal incapable of forming a hydrogen bond with another ethanal molecule despite exhibiting a bond dipole in
