The relationship between and HO - will be CC(O)C(O)C(C)O (a) two representations of the same molecule (b) diastereomers (c) enantiomers (d) anomers

Short Answer

Expert verified
Answer: There is insufficient information or an error in the problem statement. None of the mentioned relationships apply to the given molecule.

Step by step solution

01

Understand the SMILES notation

SMILES (Simplified Molecular Input Line Entry System) is a simple way to represent the structure of a chemical compound using a linear string of symbols. In this case, the SMILES code is "CC(O)C(O)C(C)O". Here's its meaning: - C: Carbon atom - O: Oxygen atom - ( ): Parentheses indicate that the atom inside the parentheses is bonded to the previous atom outside the parentheses So, the molecule's structure can be read as follows: Two carbon atoms bonded together (CC), the second carbon atom is bonded to an oxygen atom (O), then the third carbon atom bonded to another oxygen (C(O)), and finally, the fourth carbon atom bonded to a hydroxide group (C(C)O).
02

Analyze two representations of the same molecule

In this option, the molecule and its hydroxide group would be considered two different representations of the same molecule if they have identical connectivity and stereochemistry. However, there is only one molecule structure given in the SMILES code, so there is no way we can compare it to another representation. This option is not applicable.
03

Analyze diastereomers

Diastereomers are stereoisomers that are not mirror images of each other. They have different spatial arrangements of atoms or groups of atoms bonded to a tetrahedral center. In our molecule, none of the carbons bearing an oxygen atom has four different substituents. Therefore, we do not have stereocenters, and this option also does not apply.
04

Analyze enantiomers

Enantiomers are non-superimposable mirror images of a chiral molecule. Since our molecule does not have stereocenters, it cannot have enantiomers. Thus, this option is also not applicable.
05

Analyze anomers

Anomers are a specific type of diastereomers that occur in cyclic carbohydrates when a hydroxyl group and a carbonyl group are involved in the formation of a ring (examples: α-D-glucose and β-D-glucose). Our molecule is an aliphatic compound and does not contain a cyclic structure or carbonyl group. Thus, this option is also not applicable. After analyzing each option, none of them are applicable to the given molecule. It seems that there could be an error or insufficient information in the problem statement.

A chemical reaction is one in which old bonds are broken and new bonds are made. During the course of these changes a variety of intermediates are formed before a starting material is converted to final products. Formation of these intermediates depend on several factors like bond energies, kinetics of the reactions etc. Identify the correct statement among the following. (a) An electrophile has always a positive charge. (b) \(\mathrm{CN}^{-}\) can act as an ambident nucleophile. (c) The carbon species A formed is a methyl carbanion. (d) In \(\mathrm{CH}_{3} \mathrm{MgBr}\), the methyl group carries slight positive charge.

In which of the following reactions, new chiral centre(s) is/are generated. (a) \(\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_{3} \stackrel{\text { Baeyer'sreagent }}{\longrightarrow}\) (b) \(\mathrm{CH}_{3} \mathrm{CH}=\mathrm{CH}-\mathrm{CH}_{3}+\mathrm{HBr} \rightarrow\) (c) (d) \(\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}_{2}+\mathrm{HCl} \rightarrow\)

The isomeric cis \(-2\) -butene and trans 2 -butene differ in (a) the products obtained by addition of \(\mathrm{HBr}\) (b) their reduction products on hydrogenation (c) their products on ozonolysis (d) the products they give on bromine addition
