Interpretation Introduction

(a)

Interpretation:

The structure of a five carbon alkyne that contains a ring is to be stated.

Concept introduction:

The alkynes consist of a triple bond between two carbon atoms. The general formula of alkynes is CnH2n2. The name of the alkyne compounds ends with suffix yne. Hydrocarbons can also exist in ring like structures. The saturated rings have the general formula CnH2n.

Interpretation Introduction

(b)

Interpretation:

The structure of a chiral alkyne that consists of six carbons is to be stated.

Concept introduction:

Chirality is a geometric property of molecules. Any molecule having a non-super imposable mirror image is said to be a chiral molecule. The basic requirement of chirality is the presence of an asymmetric carbon. This asymmetric carbon is known as the chiral centre. An asymmetric carbon is the one in which all the substituent are different.

Interpretation Introduction

(c)

Interpretation:

The structure of a symmetrical alkyne that consists of six carbons and gives the same product on hydroboration oxidation or acid catalyzed hydration is to be stated.

Concept introduction:

Hydroboration oxidation of alkyne is the addition of water molecule to an alkyne group by Anti-Markovnikov addition. Anti-Markovnikov addition is when the hydrogen atom is attached to the carbon atom having less number of hydrogen.

Interpretation Introduction

(d)

Interpretation:

The structure of a six carbon alkyne that can exist as diastereomers is to be stated.

Concept introduction:

Diastereomers are a type of stereoisomers. In diastereomers, the configurations of carbon atoms are different at one or more than one positions but not at all carbons. They are different from enantiomers as the enantiomers have configurations of all carbon atoms different. Diastereomers have different physical and chemical properties.
