CH3CH2CH2OH undersetH2 S o4 overset K2 C r2 O7 arrow CH3CH2CHO ( B - propanal) oversetH2 N C O N H N H2 arrow CH3CH2CH=NNHCONH2 (.C.)

$C H_{3} C H_{2} C H = NN H CON H_{2}$

$(C H_{3})_{2} C = NN H CON H_{2}$

$(C H_{3})_{2} C = NCON H N H_{2}$

$C H_{3} C H_{2} C H = NCON H N H_{2}$

$\to H_{2} NCON H N H_{2} C H_{3} C H_{2} C H = NN H CON H_{2}$ $(C)$

CH3​CH2​CH=NNHCONH2​

(CH3​)2​C=NNHCONH2​

(CH3​)2​C=NCONHNH2​

CH3​CH2​CH=NCONHNH2​

CH3​CH2​CH2​OHH2​So4​→K2​Cr2​O7​​CH3​CH2​CHO ( B - propanal) →H2​NCONHNH2​CH3​CH2​CH=NNHCONH2​ (C)

$C H_{3} C H_{2} C H = NN H CON H_{2}$

$(C H_{3})_{2} C = NN H CON H_{2}$

$(C H_{3})_{2} C = NCON H N H_{2}$

$C H_{3} C H_{2} C H = NCON H N H_{2}$
