Question

Which of the following reagent can distinguish between $1$-Butyne and $2$-Butyne?

• A. Aqueous $NaOH$
• B. Bromine water
• C. Fehlings solution
• D. Ammonical $AgN{{O}_{3}}$

Answer 1

Answer: (D)

Ammonical $AgN{{O}_{3}}$

Answer 2

$\underset{(1 - \text{Butyne})}{H_3C - CH_2C \equiv CH} {->[AgNO_3][NH_4OH]} \underset{\text{(Silver - 1 butynide)}}{CH_3CH_2C \equiv CA g}$ $\underset{\text{2 - Butyne}}{H_3C - C \equiv C - CH_3} {->[AgNO_3][NH_4OH]}$ No reaction
