The method for preparation of 1-penten-3-one from 3-pentanone is given. Concept introduction: When the α-Bromo ketones can be dehydrobrominated by base treatment to yield α,Î² unsaturated ketones. For example, 2-methyl cyclohexanone gives 2-bromo-2-methylcyclohexanone on halogenation and the α bromo ketone gives 2-methyl-2-cyclohexanone when heated in pyridine. To give: The preparation method of1-penten-3-one from 3-pentanone is given.

Question

Indicate the correct option.a) Graphite conducts electricity, being an isotropic materialb) Graphite is not a conductor of electricityc) Both are false

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
