Question:
Arrange in order of increasing acidic strength
Arrange in order of increasing acidic strength
Updated On: Jan 23, 2025
- X > Z > Y
- Z < X > Y
- X > Y > Z
- Z > X > Y
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Carboxylic acid is stronger acid than ammonium ion, hence
-COOH(X) is most acidic. $_{Z(NH_3)}^{ \, \, \, \, \, +}$ is more acidic than $_{Y(NH_3)}^{ \, \, \, \, \, +}$
due to - / effect of -COOH on Z. Hence, overall acid strength
order is
X > Z > Y
-COOH(X) is most acidic. $_{Z(NH_3)}^{ \, \, \, \, \, +}$ is more acidic than $_{Y(NH_3)}^{ \, \, \, \, \, +}$
due to - / effect of -COOH on Z. Hence, overall acid strength

- A thin stiff insulated metal wire is bent into a circular loop with its two ends extending tangentially from the same point of the loop. The wire loop has mass \( m \) and radius \( r \) and is in a uniform vertical magnetic field \( B_0 \). When a current \( I \) is passed through the loop, the loop turns about the line PQ by an angle \( \theta \). The angle \( \theta \) is given by:

- A region in the form of an equilateral triangle (in x-y plane) of height \( L \) has a uniform magnetic field \( \mathbf{B} \) pointing in the \( +z \)-direction. A conducting loop PQR, in the form of an equilateral triangle of the same height \( L \), is placed in the x-y plane with its vertex \( P \) at \( x = 0 \) in the orientation shown in the figure. At \( t = 0 \), the loop starts entering the region of the magnetic field with a uniform velocity \( \mathbf{v} \) along the \( +x \)-direction. The plane of the loop and its orientation remain unchanged throughout its motion.
