Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

From the above structure, it can be seen that there are eight carbon atoms are present in the principle chain of the compound and the atoms are bonded with triple bonds. Hence, the compound is known as alkynes. The triple bond of the structure is present at position one that is lowest possible number. The methyl substituent of the structure is present at third carbon (C3) position and one ethyl substituent is present at fourth carbon (C4) position. Therefore, the name of the compound is 4 − ethyl − 3 − methyl − 1 − octyne. The representation of the carbon position in a structure is given below −

Interpretation Introduction

Interpretation:

The name of the following alkyne is to be determined

Concept Introduction:

The unsaturated hydrocarbon is a group of hydrocarbons and also known as alkenes or alkynes. This structure is formed because of the presence of triple or double bonds. Alkynes or hydrocarbons consists at least triple bond while alkynes consist at least one carbon-carbon double bon in the main chain.
