What are the aromatic nitro compounds?
The aromatic nitrocompounds are a group of organic chemicals headed by nitrobenzene (C6H5NO2) and derived from benzene and its homologues (toluene and xylene), naphthalene and anthracene by replacement of one or more hydrogen atoms by a nitro- group (NO2).
Is nitro group aromatic?
Nitroaromatic compounds are among the largest and most important groups of industrial chemicals in use today. These compounds are organic molecules that consist of at least one nitro group (-NO2) attached to an aromatic ring.
How do you name nitro compounds?
According to the IUPAC nomenclature nitro compounds are named by adding the permanent prefix ‘nitro’ to the name of the parent hydride. The position of any substitutent if present is however indicated by the Arabic numbers 1,2,3…….etc with the carbon bearing the nitro group gets the lowest priority number.
How will you detect the presence of nitro group in an aromatic compound?
Hint: Mulliken Barker test is used to detect the presence of a mono nitro group in the compound. The presence of the nitro group can be observed by the shiny silver mirror that is formed at the end of the reaction.
What are general properties of aromatic nitro compounds?
Physical Properties of Nitro Compounds Physical state, color, odour: Nitroalkanes are colorless, pleasant smelling liquids. Aromatic nitro compounds can be neither pale yellow liquids or solids with distinct smells. For example, nitrobenzene is a pale yellow liquid having the smell of bitter almonds.
What happens when aromatic nitro compounds such as nitrobenzene is nitrated?
A nitro compound ordinarily is made by the reaction, called nitration, between nitric acid and an organic compound. Nitration of aromatic compounds, such as benzene or toluene, is commonly effected by treating them with a mixture of nitric and sulfuric acids at temperatures of 100° C or lower.
What is NO2 called as a substituent?
Note. The nitro (NO 2) group is a common substituent in aromatic compounds. Many nitro compounds are explosive, most notably 2,4,6-trinitrotoluene (TNT).
What is the functional group of nitro?
The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally. The nitro group is also strongly electron-withdrawing. Because of this property, C−H bonds alpha (adjacent) to the nitro group can be acidic.
What is the functional group of nitro compounds?
Nitro compounds are organic compounds that contain one or more nitro functional groups (−NO 2). The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally.
What is true about IUPAC naming of organic compounds?
IUPAC nomenclature is based on naming a molecule’s longest chain of carbons connected by single bonds, whether in a continuous chain or in a ring. All deviations, either multiple bonds or atoms other than carbon and hydrogen, are indicated by prefixes or suffixes according to a specific set of priorities.
