The structure of petroselenic acid and its consistency with the given observations is to be stated. Concept introduction: The hydrogenation reaction convert an unsaturated hydrocarbon into a saturated hydrocarbon in the presence of metal catalyst like Pt, Pd, Ni . The reaction of an alkene with warm KMnO 4 cleaves the double bond and converts it into dioic acid. The protons that are attached directly to an alkene is called vinylic protons. The NMR spectrum shows absorption of vinylic protons split by coupling constant (that are cis to each other) in the range of 6 − 15 Hz . To determine: The structure of petroselenic acid and its consistency with the given observations.

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 .
