Question

Match List I with List II:

List I	List II
A. Spinal poison	I. Carbon monoxide
B. NH2-	II. Linear
C. NH4+	III. Tetrahedral
D. [PtCl4]-	IV. Square planar

Choose the correct answer from the options given below:

• A. (A)- (II), (B)- (III), (C)- (I), (D)- (IV)
• B. (A)- (III), (B)- (II), (C)- (I), (D)- (IV)
• C. (A)- (II), (B)- (I), (C)- (III), (D)- (IV)
• D. (A)- (III), (B)- (IV), (C)- (I), (D)- (II)

Hint:

The shape of ions can be predicted using VSEPR theory based on the number of bonding pairs and lone pairs on the central atom.

Answer 1

The Correct Option is C

The \(\text{ICl}_2^-\) ion possesses a linear geometry.
The \(\text{NH}_2^-\) ion exhibits a V-shaped (angular) geometry.
The \(\text{NH}_4^+\) ion displays a tetrahedral geometry.
The \([\text{PtCl}_4]^-\) ion adopts a square planar geometry.
