Directions: Each question contains Statement- 1 and Statement- 2 and has the following choices (a), (b), (c) and (d), out of which ONLY ONE is correct. (a) Statement- 1 is True, Statement- 2 is True; Statement- 2 is a correct explanation for Statement- 1 (b) Statement- 1 is True, Statement- 2 is True; Statement- 2 is NOT a correct explanation for Statement- 1 (c) Statement- 1 is True, Statement- 2 is False (d) Statement- 1 is False, Statement- 2 is True Statement 1 Acetals and ketals are unstable in aqueous acid conditions, but quite stable to alkaline conditions. and Statement 2 A weaker base like (OH) cannot displace a stronger base like (OR) found in acetals and ketals.

Step by step solution

01

Analyze Statement 1

Let's first analyze Statement 1: Acetals and ketals are unstable in aqueous acid conditions, but quite stable to alkaline conditions. This statement is True. Acetals and ketals are formed from the reaction between an aldehyde or ketone with an alcohol in the presence of an acid catalyst, and they can easily hydrolyze back to their respective aldehyde/ketone and alcohol under acidic conditions. However, they are more stable under alkaline conditions because the hydrolysis reaction does not readily occur.

02

Analyze Statement 2

Now let's analyze Statement 2: A weaker base like (OH) cannot displace a stronger base like (OR) found in acetals and ketals. This statement is True as well. In the general sense, a stronger base displaces a weaker base in a reaction. In this case, the alkoxide ion (OR) is a stronger base than the hydroxide ion (OH). When we consider the equilibrium between the reactants and products, the less stable hydroxide ion (OH) does not notably favor the formation of acetals or ketals.

03

Evaluate the relationship between Statement 1 and Statement 2

Now, let's decide if Statement 2 is a correct explanation for Statement 1. Statement 2 explains why acetals and ketals are more stable in alkaline conditions (due to the weaker base OH not being able to displace OR). Therefore, Statement 2 is a correct explanation for Statement 1.

04

Choose the correct answer

Based on the analysis, Statement 1 is True, Statement 2 is True, and Statement 2 is a correct explanation for Statement 1. So, the correct answer is (a) Statement- 1 is True, Statement- 2 is True; Statement- 2 is a correct explanation for Statement- 1.
