Question:
Which one of the following molecules has maximum number of lone pairs of electrons?
Which one of the following molecules has maximum number of lone pairs of electrons?
Show Hint
Remember:
\[
XeF_2 \rightarrow 3 \text{ lone pairs}
\]
\[
ClF_3 \rightarrow 2 \text{ lone pairs}
\]
\[
SF_4 \rightarrow 1 \text{ lone pair}
\]

The Correct Option is A
Solution and Explanation
Concept:
Using VSEPR theory, determine the number of lone pairs present on the central atom.
Step 1: Count lone pairs.
For \[ XeF_2 \] central Xe contains \[ 3 \text{ lone pairs} \] For \[ ClF_3 \] central Cl contains \[ 2 \text{ lone pairs} \] For \[ SF_4 \] central S contains \[ 1 \text{ lone pair} \] For \[ CF_4 \] central C contains \[ 0 \text{ lone pair} \]
Step 2: Compare values.
Maximum lone pairs are present in \[ XeF_2 \] \[ \boxed{XeF_2} \]
Step 1: Count lone pairs.
