Question

How do nitro compound shows isomerism with nitrites?

Answer 1

 

Nitro alkanes are derivatives of alkanes. They are isomeric to nitrites (esters) classified as primary, secondary and tertiary depending on the nature of carbon atom to which nitro group is linked.

Primary nitro alkane        Secondary Nitro alkane            Tertiary nitro alkane

—NO2 group is an ambident group. If it attacks through nitrogen. It is called nitro and if it attacks through oxygen atom, it is called nitrite. Hence nitrites and nitro compounds are isomers.

Answer 2

Answer:

Hence nitrites and nitro compounds are isomers. nucleophiles Evidences show that nitrogen is attached to one of the oxygen atoms by a double bond and to the other by a dative bond. The resonance hybrid is shown as under which confirms the spectroscopic evidence that both nitrogen – oxygen bonds have same bond length.
