MCQ
Which gives difference between aldehyde and ketone
- AFehling's solution
- BTollen's reagent
- CSchiff's reagent
- ✓All of these
✓
Answer
Correct option: D.
All of these
d
(d) Fehling solution $⇒$ Alkaline $CuS{O_4} + Na - K$ tartarate
(d) Fehling solution $⇒$ Alkaline $CuS{O_4} + Na - K$ tartarate
Tollen’s reagent $⇒$ $N{H_4}OH + AgN{O_3}$
Schiff’s reagent $⇒$ $P-$rosaniline hydrochloride or magneta
Benedict’s solution $⇒$ Alkaline $CuS{O_4} + $Citrate ions
All these reagents are used to distinguish between aldehydes and ketones.
Aldehydes reacts with all these reagents while ketones do not react.

A large spherical mass $M$ is fixed at one position and two identical point masses $m$ are kept on a line passing through the centre of $M$ (see figure). The point masses are connected by a rigid massless rod of length $\ell$ and this assembly is free to move along the line connecting them. All three masses interact only through their mutual gravitational interaction. When the point mass nearer to $M$ is at a distance $r =3 \ell$ from $M$, the tension in the rod is zero for $m=k\left(\frac{M}{288}\right)$. The value of $k$ is
