The structure of the isomers that would expect to obtain in the mononitration of m-methoxybenzaldehyde should be determined. Concept introduction: The electrophilic aromatic substitution is the type of reaction in which an electrophile substitutes the hydrogen atom of benzene. Nitration of benzene is an example of electrophilic aromatic substitution. The activating groups are the groups that have the ability to donate the electron density to the benzene ring. The deactivating groups are the groups that have the ability to withdraw the electron density to the benzene ring. The ortho and para directing groups are the activating groups while meta direction groups are deactivating groups.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

What are the three alkenes formed in the acid-catalyzed dehydration of 2-pentanol? Propose the mechanism of their formation.

Describe the product formed as a result of the reaction between cyclohexanone and 3-butene-2-one by also writing the mechanism of the reaction.

1. The ketone 2-heptanone has been identified as contributing to the odor of a number of dairy products, including condensed milk and cheddar cheese. Describe the synthesis of 2-heptanone from acetylene and any necessary organic and inorganic reagents. 2. Compound A has the molecular formula C14H25Br and was obtained by reaction of sodium acetylide (HC≡CNa) )with 1,12-dibromododecane. On treatment of compound A with sodium amide, it was converted to compound B (C14H24). Ozonolysis of compound B gave the diacid HO2C(CH2)12CO2H. Catalytic hydrogenation of compound B over Lindlar palladium gave compound C (C14H26), while hydrogenation over platinum gave compound D (C14H28). Sodium-ammonia reduction of compound B gave compound E (C14H26). Both C and E yielded O═CH(CH2)12CH═O on ozonolysis. Assign structures to compound A through E so as to be consistent with the observed transformations.
