Question

Identify $X$, $Y$ and $Z$ in the given reaction: ${CH_2=CH2->[Br_2][CCl_4]X->[NaCN][2\,moles]Y->[LiAlH_4]Z}$

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (D)

d

Answer 2

${CH2=CH2->[Br_2][CCl_4]}$ $\underset{\text{(X)}}{ {BrCH2-CH2Br}} {->[2NaCN]}$ $\underset{\text{(Y)}}{ {NCCH2CH2CN}} {->[LiAlH_4]}$ $\underset{\text{(1.4- Diaminobutane)}_{(Z)}}{ {H2NCH2CH2CH2CH2NH2}}$
