`RCH=CH_(2) + BH_(3) rarr A overset(-OH//NH_(2)Cl)rarr` उत्पाद, उत्पाद होगा ।

Options

A. `RCH_(2)-CH_(2)-NH_(2)`
B. `R underset(underset(NH_(2))(|))(C )H-underset(underset(NH_(2))(|))(C )H_(2)`
C. `R-CH_(2)-NH_(2)`
D. `RNH_(2) + CH_(2)=CH -NH_(2)`

Answer

A

Explanation

A ट्राइऐल्किल बोरेन है जो NaOH तथा `NH_(2)Cl` से क्रिया कर ऐल्किल ऐमीन बनाता है।
`R-CN = CH_(2) + BH_(3) rarr underset((A ))((R-CH_(2)-CH_(2)-)_(3))B overset(NH_(2)Cl)rarr underset("उत्पाद")(R-CH_(2)-CH_(2)-NH_(2))`
`underset((A ))((R-CH_(2)-CH_(2))_(3))-B + overset(..)(N)H_(2)Cl rarr (R-CH_(2)-CH_(2)-)_(2) underset(underset(CH_(2)-CH_(2)-R)(|))overset(Θ)(B)-underset(underset(H)(|))overset(oplus)(N)H-Cl`
`underset("ऐल्किल ऐमीन") (R-CH_(2)-CH_(2)-NH_(2))underset(-B(OH)_(3))overset(H_(2)O)larr (R-CH_(2)-CH_(2)-)_(2)B-underset(underset(CH_(2)CH_(2)-R)(|))(N)H+Cl^(-)overset(-H^(+))larr (R-CH_(2)-CH_(2)-)_(2) underset(underset(CH_(2)CH_(2)_R)(|))overset(Θ)(B)-NH-Cl`
