In order to prepare a `1_(@)` amine from an alkyl halide with simultaneous addition of one `CH_(2)` group in the carbon chain, the reagent used as source of nitrogen is:

A

Sodium amide, `NaNH_(2)`

B

Sodium azide, `NaN_(3)`

C

Potassium cyanide, `KCN`

D

Potassium phthalimide, `C_(6)H_(4)(CO)_(2)N^(-)K^(+)`

Text Solution

Verified by Experts

The correct Answer is:
C
Cyanides on reduction give `1^(@)` amines with one C atom more
`RX overset(KCN)underset(-KX) rarr RCN overset(Na. C_(2)H_(5)OH)rarr underset(1^(@)-" Amine")`

A cottage industry manufactures pedestal lamps and wooden shades, each requiring the use of a grinding cutting machine and a sprayer . It takes 2 h on grinding cutting machine and 3 h on the sprayer to manufacture a pedestal lamp . It takes 1 h on the grinding cutting machine and 2 h on the sprayer to manufacture a shade . On any day, the sprayer is available for at the most 20 h and the grinding cutting machine for at the most 12 h . The profit from the sale of a lamp is Rs 5 and that from a shade is Rs 3 . Assuming that the manufacture can sell all the lamps and should he schedule his daily production in order to miximize his profit ?

Vladimir Markovnikov rule : Alkenes undergo electrophilic addition reactions. It is triggered by the acid acting as a electrophile toward t-electrons of the double bond. Markovnikov's rule states that when an unsymmetrically substituted alkene reacts with a hydrogen halide, the hydrogen atom adds to the carbon that has the greater number of hydrogen, e.g., Identify the major products r_1, r_2, and r_3 in the given reactions.
