$$R-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-NHOH$$

TuteeHUB · Answer

$$R-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-NH.C{{H}_{3}}$$

TuteeHUB · Answer

$$R-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-O.N{{H}_{4}}$$

TuteeHUB · Answer

$$R-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-N{{H}_{2}}$$

1.	Indicate which nitrogen compound amongst the following would undergo Hofmann's reaction (i.e. reaction with \[B{{r}_{2}}\] and strong KOH) to furnish the primary amine (\[R-N{{H}_{2}}\]) [CBSE PMT 1989]
A.	\[R-\overset{O}{\mathop{\overset{\|\|}{\mathop{C}}\,}}\,-NH.C{{H}_{3}}\]
B.	\[R-\overset{O}{\mathop{\overset{\|\|}{\mathop{C}}\,}}\,-O.N{{H}_{4}}\]
C.	\[R-\overset{O}{\mathop{\overset{\|\|}{\mathop{C}}\,}}\,-N{{H}_{2}}\]
D.	\[R-\overset{O}{\mathop{\overset{\|\|}{\mathop{C}}\,}}\,-NHOH\]
Answer» D. \[R-\overset{O}{\mathop{\overset{\|\|}{\mathop{C}}\,}}\,-NHOH\]
