The IUPAC name for the given unsaturated hydrocarbon has to be assigned. Concept Introduction: IUPAC nomenclature for alkyne : The suffix –ane has to be replaced with the suffix –yne. This is used to indicate the presence of triple bond. The longest continuous chain of carbon atoms has to be chosen that contains both carbon atoms of the triple bond. The parent carbon chain has to be numbered in a way so that the numbering begins at the end near to the triple bond. In case if the triple bond is equidistant from both ends, then numbering has to be done from the end that is closer to substituents. The position of the triple bond has to be given a single number which is lower‑numbered carbon atom that is present in the triple bond. Suffixes like –diyne, -triyne, -tetryne, and so on are used when the compound contains more than one triple bond.

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 .
