Chapter 4: Problem 111

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 Nucleophilicity does not always match with basicity. and Statement 2 While nucleophilicity is more related to size, polarizability and steric factors, the basicity is the ability to abstract a proton from a substrate.

Short Answer

Expert verified
Explain your answer based on the provided statements. Answer: No, nucleophilicity and basicity do not always match up. While both involve interactions with other molecules, nucleophilicity is related to the ability to donate electrons for forming a chemical bond and is influenced by size, polarizability, and steric factors, whereas basicity is defined as the ability to accept a proton (H+ ion) from a substrate. Despite some similarities, they are influenced by different factors and thus do not necessarily match up.

Step by step solution

01

Statement-1: Nucleophilicity does not always match with basicity.

This statement is true. Nucleophilicity refers to the ability of an atom or molecule to donate a pair of electrons to another molecule to form a chemical bond. Basicity, on the other hand, refers to the ability of a molecule to accept a proton (H+, a hydrogen ion). While they may exhibit similar trends, nucleophilicity and basicity do not necessarily match up.
02

Statement-2: While nucleophilicity is more related to size, polarizability and steric factors, the basicity is the ability to abstract a proton from a substrate.

This statement is also true. The factors affecting nucleophilicity include size, polarizability, and steric hindrance. Larger, more polarizable, and less sterically hindered molecules tend to be better nucleophiles. Basicity is related to the ability of a molecule to accept a proton; it is related to different factors than nucleophilicity. Now, we can determine whether Statement-2 is a correct explanation for Statement-1.
03

Explanation Relationship

Statement-1 is true and Statement-2 is true; however, Statement-2 does not directly explain why nucleophilicity and basicity do not always match up. They both describe the characteristics of nucleophilicity and basicity separately, but Statement-2 does not provide a strong correlation or explanation for the difference. Based on our analysis, the correct answer choice is: (b) Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1
