Concept explainers
Interpretation:
The given compounds react as an electrophile or a nucleophile is to be classified.
Concept introduction:
The compound capable of donating a pair of electrons to an electrophile to create a new bond, is known as nucleophile. It seeks a positive center. Lewis bases are considered as nucleophiles.
Negative charged species or electron rich species act as nucleophiles
All those compounds that have the tendency of attracting electron rich center, are known as electrophiles. They are considered as a positively charged or neutral species. Lewis acids are electrophiles.
Positively charged species or electron deficient species act as electrophiles.
In resonance structures, the electrons can move in order to help stabilizing the molecule and, the compound should have same number of electrons.

- True or False Considering that two carbon chains have equal number of carbons, but one has Fluorine and the other has Iodine, the one with iodine will have a higher boiling point. Mild oxidation of alkenes results to similar product as that of nucleophilic addition of water to aldehydes.arrow_forwardWhat is electrophilic addition in its very basic sense?arrow_forwardAn electron-deficient carbon atom reacts with a nucleophile, symbolized as: Nu−.

What does this mean and how does it arise? 2) The carbon-oxygen double bond is readily attacked by nucleophiles like cyanide ions or ammonia. (i) What do you understand by the term nucleophile? (ii) Which part of the carbon-oxygen double bond is attractive to nucleophiles? 3) Why is there a difference between aldehydes and ketones in their response to oxidizing agents such as potassium dichromate(VI) solution acidified with dilute sulfuric acid?arrow_forwardMarkovnikov's rule can best be explained by considering * a) the number of hydrogen atoms attached to each of the double bond carbons atoms. b) the number of alkyl groups attached to each of the double bond carbons atoms. c) the relative stabilities of the carbocations that can be formed from the alkene. d) the spatial arrangement of the groups around the double bond. e) All of the above are good explanations for Markovnikov's rule.arrow_forward
- Oa) An amine can be formed when 2-iodopentane is heated with ammonia in a sealed tube. This is an example of a nucleophilic substitution reaction. i) Provide a full equation (using condensed formula) for this reaction. You should name the reactants and the overall products as part of your response. ii) Name the organic product formed from this reaction and draw it's displayed structure. iii) Provide a 'curly arrow' mechanism (in displayed formula) with an accompanying explanation for this process. iv) Describe a characteristic test (with the result that would be observed) to show the presence of the amine produced upon completion of the nucleophilic substitution reaction. b) The amine produced in the above reaction forms a mixture of two optical isomers. i) Draw the 3D structures of the two isomers of the amine product that you named and produced a drawing of in part a ii). ii) With reference to a different named example, explain the term 'optical isomer'. You should draw the 3D…arrow_forwardIn each of the following classes of organic compounds, write (by express formula) two molecules each with at least one aromatic group and one alkyl group with a total of 10 carbons.
