Each of the given alkyne compound is to be named. Concept Introduction: Hydrocarbons are the organic compounds which contain only carbon and hydrogen atoms. Alkynes are the unsaturated hydrocarbons which contain at least one triple bond. The general molecular formula for the alkyne is C n H 2 n − 2 . The IUPAC rules for naming the compound are as follows: The longest continuous chain is to be selected and then the number of carbon atoms is counted in that chain. If a substituent is present in the longest chain, then name each substituent according to the number of carbon atoms present in the substituent. The base chain is to be numbered in such a way that the substituent gets the lowest number. Finally, the compound’s name is written in such a way that the number of the substituent is followed by a dash, after that the name of the substituent is written and then the base name of the compound.

Answer 1

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 .

Interpretation Introduction

Interpretation:

Each of the given alkyne compound is to be named.

Concept Introduction:

Hydrocarbons are the organic compounds which contain only carbon and hydrogen atoms.

Alkynes are the unsaturated hydrocarbons which contain at least one triple bond.

The general molecular formula for the alkyne is CnH2n−2.

The IUPAC rules for naming the compound are as follows:

The longest continuous chain is to be selected and then the number of carbon atoms is counted in that chain.

If a substituent is present in the longest chain, then name each substituent according to the number of carbon atoms present in the substituent.

The base chain is to be numbered in such a way that the substituent gets the lowest number.

Finally, the compound’s name is written in such a way that the number of the substituent is followed by a dash, after that the name of the substituent is written and then the base name of the compound.
