Hydrocarbons Ques 48

48. In the reaction

$H-C \equiv CH \frac{(1) NaNH_2 / \text{ liq. } NH_3}{(2) CH_3 CH_2 Br} X$

$ \frac{\text{ (1) } NaNH_2 / \text{ liq. } NH_3}{\text{ (2) } CH_3 CH_2 Br} Y $

$X$ and $Y$ are

[2016]

(a) $X=1$-Butyne; $Y=3$-Hexyne

(b) $X=2$-Butyne; $Y=3$-Hexyne

(c) $X=2$-Butyne; $Y=2$-Hexyne

(d) $X=1$-Butyne; $Y=2$-Hexyne

Show Answer

Solution:

  1. (a)

$ HC \equiv CH \xrightarrow[\text{ liq. } NH_3]{NaNH_2} HC \equiv \overline{C} \stackrel{\oplus}{Na} $
