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.

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 .

2) (4 pt) After the reaction was completed, the student collected the following data. Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization. Student B's data: Crude product data "Pure" product data after recrystallization Crude mass: 0.93 g grey solid Crude mp: 96-106 °C Crude % yield: Pure mass: 0.39 g white solid Pure mp: 111-113 °C Pure % yield: a) Calculate the crude and pure percent yields for the student's reaction. b) Summarize what is indicated by the crude and pure melting points.
