MCQ
The reagent which could distinguish between $1-$ hexyne and $1-$ hexene is 
  • Tollen's reagent
  • B
    Baeyer's reagent
  • C
    Bromine water test
  • D
    All

Answer

Correct option: A.
Tollen's reagent
a
$Ag \left( NH _3\right)_2^{+}$is called Tollen's reagent.

It reacts with terminal alkynes ($1-$hexyne) but not with alkenes ($1-$hexene).

$CH \equiv CCH _2 CH _2 CH _3+ Ag \left( NH _3\right)_2^{+} \rightarrow CH _3 CH _2 CH _2 C \equiv C - Ag + NH _4 OH$

A charge $Q$ is uniformly distributed over the surface of nonconducting disc of radius $R$. The disc rotates about an axis perpendicular to its plane and passing through its centre with an angular velocity $\omega$. As a result of this rotation a magnetic field ofinduction $B$ is obtained at the centre of the disc. If we keep both the amount of charge placed on the disc and its angular velocity to be constant and vary the radius of the disc then the variation of the magnetic induction at the centre of the disc will be represented by the figure
