A solution of phenol in chloroform when treated with aqueous NaOH gives compound P as a major product. The mass percentage of carbon in P is ______. (to the nearest integer)
(Atomic mass : C = 12; H = 1; O = 16)
(Atomic mass : C = 12; H = 1; O = 16)
Show Hint
Correct Answer: 69
Solution and Explanation
Molar mass = \(7\times12 + 6\times1 + 2\times16 = 84 + 6 + 32 = 122\).
Mass % of C = \(\frac{84}{122}\times100 = 68.85\approx 69\).
Answer: 69

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
