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 .

Structural formula where a line represent carbon‑carbon bond and the carbon atom is considered to be present in each point and the end of lines is known as Line-angle structural formula. To indicate a double bond between carbon atom, double line is used.

Interpretation Introduction

Interpretation:

The IUPAC name for the given compound has to be written.

Concept Introduction:

IUPAC nomenclature for alkene: There are about eight rules to be followed in giving IUPAC name for alkene.

The suffix –ane has to be replaced with the suffix –ene. This is used to indicate the presence of double bond.

The longest continuous chain of carbon atoms has to be chosen that contains both carbon atoms of the double bond.

The parent carbon chain has to be numbered in a way so that the numbering begins at the end near to the double bond. In case if the double bond is equidistant from both ends, then numbering has to be done from the end that is closer to substituents.

The position of the double bond has to be given a single number which is lower‑numbered carbon atom that is present in the double bond.

Suffixes like –diene, -triene, -tetrene, and so on are used when the compound contains more than one double bond.

In case of cycloalkenes which do not have any substitution, the numbering is not needed to locate the double bond because the bond is assumed to be between the carbons 1 and 2.

In case if substituents are present in cycloalkene, then the double‑bonded carbon atoms are numbered 1 and 2 in a direction where the substituent gets the lower number.

If the cycloalkenes contain more than one double bond, then one double bond is assigned the numbers 1 and 2 followed by the other double bond so that the lowest number possible is given.
