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.
