Chapter 1: Problem 52

A meso compound (a) is an achiral molecule, which contain chiral carbons. (b) contains a plane of symmetry or a centre of symmetry. (c) is optically inactive due to internal compensation. (d) is characterized by all the above.

Short Answer

Expert verified
a) an achiral molecule which contains chiral carbons b) contains a plane of symmetry or a center of symmetry c) is optically inactive due to internal compensation Answer: Statements (b) and (c) accurately describe a meso compound.

Step by step solution

01

Analyze statement (a)

Statement (a) says that a meso compound is an achiral molecule which contains chiral carbons. This statement is partially correct, as meso compounds do have chiral centers. However, meso compounds are not considered achiral, as they have an internal plane of symmetry, causing them to be optically inactive.
02

Analyze statement (b)

Statement (b) says that a meso compound contains a plane of symmetry or a center of symmetry. This statement is correct as meso compounds have an internal plane of symmetry. This characteristic is a defining feature of meso compounds.
03

Analyze statement (c)

Statement (c) says that a meso compound is optically inactive due to internal compensation. This statement is accurate, as the internal plane of symmetry causes the compound to be optically inactive, despite having chiral centers.
04

Analyze statement (d)

Statement (d) says that a meso compound is characterized by all the above statements. As we analyzed each statement and found that (b) and (c) are correct, while statement (a) is partially correct, statement (d) is not entirely accurate.
05

Determine the correct answer

Based on our analysis, statement (b) and statement (c) accurately describe a meso compound. Statement (a) is only partially correct, and statement (d) is not entirely accurate since statement (a) is not completely correct. Therefore, the answer is a combination of statement (b) and statement (c), as both of these correctly describe a meso compound.
