Chapter 23, Problem 68GQ

Interpretation Introduction

Interpretation:

The structures of $2-bu\tan ol$ and its mirror image has to be drwan and both structures are superimposable or not has to be identified.

Concept introduction:

Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry).IUPAC name consists of three parts, namely Prefix, suffix and root word.

Prefix- Represents the substituent present in the molecule and its position in the root name.

Suffix- Denotes the presence of functional group if any in the molecule.  It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc.  To add suffix to name a compound, the suffix “-ane” in the parent alkane is replaced by the respective suffix, which corresponds to the functional group present in the given compound.  For carboxylic acid, suffix “-oic” will be added, for alcohol, suffix “-ol” will be added and so on

Root word - Represents the longest continuous carbon skeleton of the organic molecule.

A chiral carbon is the carbon atom which is substituted to four different groups. Due to presence of chiral carbon a molecule become chiral and it gives optical isomers also that is $\text{R and S}$ isomers. For example,

All the substituents are different hence it is a chiral carbon and so molecule.
