| Which of the following will produce isopropyl amine- |
| (I) \[{{(C{{H}_{3}})}_{2}}CO\xrightarrow{N{{H}_{2}}OH}X\xrightarrow{LiAl{{H}_{4}}}\] |
| (II) \[C{{H}_{3}}-C{{H}_{2}}-CHO\xrightarrow[heat]{N{{H}_{3}}}X\xrightarrow{LiAl{{H}_{4}}}\] |
| (III) \[{{(C{{H}_{3}})}_{2}}CH-OH+PC{{l}_{5}}\xrightarrow{{}}X\xrightarrow{N{{H}_{3}}}\] |
| (IV) \[C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}+N{{H}_{2}}\xrightarrow{heat}\] |
A) I, II
B) II, III
C) I, III
D) IV only
Correct Answer: C
Solution :
[c] \[{{(C{{H}_{3}})}_{2}}CO\xrightarrow{N{{H}_{2}}OH}{{(C{{H}_{3}})}_{2}}CH=N-OH\] \[\xrightarrow{LiAl{{H}_{4}}}{{\left( C{{H}_{3}} \right)}_{2}}CHN{{H}_{2}}\] \[{{(C{{H}_{3}})}_{2}}CHOH\xrightarrow{PC{{l}_{5}}}{{(C{{H}_{3}})}_{2}}CHCl\xrightarrow{N{{H}_{3}}}\] \[{{\left( C{{H}_{3}} \right)}_{2}}CHN{{H}_{2}}\]
