A primary amine, RNH₂ can be reacted with CH₃-X to get secondary amine, R-NHCH₃ but the only disadvantage is that \({ 3 }^{ \circ }\) amine and quaternary ammonium salts are also obtained as side products. Can you suggest a method where RNH₂ forms only \({ 2 }^{ \circ }\) amine

Write the IUPAC name of the following compounds:
\({ H }_{ 3 }C-\underset { \overset { | }{ { H }_{ 3 }C } }{ N } -\overset { \overset { { CH }_{ 3 } }{ | } }{ \underset { \overset { | }{ { C }_{ 2 }{ H }_{ 5 } } }{ C } } -{ CH }_{ 2 }{ CH }_{ 3 }\)

What is diazotisation? Why are benzenediazonium salts more stable than alkanediazonium salts?

In the following sequence of reactions, write the structures of the compounds P, Q and R.
\(\ P\overset { B{ r }_{ 2 } }{ \underset { Sn/HCI }{ \longrightarrow } } Q\overset { (i)\ { NaNO }_{ 2 }\ /\ HCI,\ 273-278K }{ \underset { (ii)\ { H }_{ 2 }O/{ H }_{ 3 }{ PO }_{ 2 } }{ \longrightarrow } } R\overset { { KMnO }_{ 4 }\ /\ { OH }^{ - } }{ \longrightarrow } o-Bromobenzoic\ acid\)
