Question

in hybridization in incl₄⁻. select the single best answer.
○ sp²
○ sp³
○ sp
○ sp³d
○ sp³d²

Explanation:

Step1: Determine central atom

In $\text{InCl}_4^-$, indium (In) is the central atom.

Step2: Calculate valence - electron number of central atom

In has 3 valence electrons. The negative charge of 1 adds 1 more electron, so total valence electrons of In in $\text{InCl}_4^-$ is 4.

Step3: Determine number of bonding pairs and lone pairs

In $\text{InCl}_4^-$, In forms 4 bonds with Cl atoms and has 0 lone - pairs. The steric number (SN) is the sum of bonding pairs and lone pairs. Here, SN=4 (4 bonding pairs + 0 lone pairs).

Step4: Relate steric number to hybridization

When the steric number is 4, the hybridization is $sp^3$.

Answer:

$sp^3$
