Benzene Ring With Ketone Attached

The old name for phenylamine is aniline and you could also reasonably call it.

Benzene ring with ketone attached.

As it contains only carbon and hydrogen atoms benzene is classed as a hydrocarbon. Halo arenes aryl a romatic halides. This is known as the clemmensen reduction and involves heating the ketone with amalgamated zinc a mixture of zinc and mercury and concentrated hydrochloric acid for a long time. Remember that the phenyl group is a benzene ring minus a hydrogen atom c 6 h 5.

Recall that toluene is a benzene ring with a single methyl substituent. Select the correct choice below. The simplified formula for this is c 6 h 5 cl. 1 2 or 1 3 or 1 4 dichlorobenzene c 6 h 4 cl 2.

For example chlorine cl attached to a phenyl group would be named chlorobenzene chloro benzene. C 7 h 7 cl chloromethylbenzene or chloromethyl benzene benzyl chloride. If you draw a benzene ring with one group attached you have drawn a phenyl group. Since there is only one substituent on the benzene ring we do not have to indicate its position on the benzene ring as it can freely rotate around and you would end up getting the same compound figure 8.

Because of the full or partial positive charge on the element directly attached to the ring for each of these groups they all have a moderate to strong electron withdrawing inductive effect known as the i effect. Ketones contain an oxygen atom. During the third step alcl 4 returns to remove a proton from the benzene ring which enables the ring to return to aromaticity. Different groups effects on benzene carbonyls sulfonic acids and nitro.

For example h 2 c o is methanal more commonly called formaldehyde since an aldehyde carbonyl group must always lie at the end of a carbon chain it is always is given the 1 location position in numbering and it is not necessary to include it in the name. Phenylethanone can also be reduced to produce ethylbenzene. This is a simple example of a halogen attached to the benzene ring. The iupac system of nomenclature assigns a characteristic suffix al to aldehydes.

The name is self obvious. Ketones have higher boiling points than the corresponding alkanes. The oxygen atom in ketones is directly attached to a hydrogen atom. Chlorobenzene c 6 h 5 cl and.

In doing so the original alcl 3 is regenerated for use again along with hcl. Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals. It is not a true aryl halogen compound the halogen atom is in a non aromatic side chain so it. You could therefore although you never do call it phenyl chloride.

Or aryl halide aromatic halogen compounds the halogen is directly attached to the benzene ring. Phenylamine is a primary amine and contains the nh 2 group attached to a benzene ring. Most importantly we have the first part of the final product of the reaction which is a ketone.
