Correct the increasing order of acidity is as
Updated On: Jun 27, 2024
- $H_2O,C_2H_2,H_2CO_3$, phenol
- $C_2H_2, H_2O, H_2CO_3,$ phenol
- Phenol, $C_2H_2,H_2CO_3,H_2O$
- C$_2H_2,H_2O, phenol \, and \, H_2CO_3$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
C$_2H_2$ have acidic nature but it is less acidic than
water but phenol is more acidic than water due to
resonance stabilisation of phenoxide ion. H$_2CO_3$ is
most acidic due to resonating stabilisation of
carbonate ion (CO$_3^{2-}$).
Thus, the correct order is
$ \, \, \, \, \, \, C_2H_2 < H_20 < phenol < H_2CO_3$
water but phenol is more acidic than water due to
resonance stabilisation of phenoxide ion. H$_2CO_3$ is
most acidic due to resonating stabilisation of
carbonate ion (CO$_3^{2-}$).
Thus, the correct order is
$ \, \, \, \, \, \, C_2H_2 < H_20 < phenol < H_2CO_3$

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :
