Question

Molecular shape of ${XeF}_3^{+}$, ${S{F}_3}^{+}$ and ${C{F}_3}^{+}$ are ________ .

• A. the same with 2, 1 and 0 lone pairs of electrons respectively
• B. different with 2, 1 and 0 lone pairs of electrons respectively
• C. different with 0, 1 and 2 lone pairs of electrons respectively
• D. the same with 2, 0 and 1 lone pairs of electrons respectively

Answer 1

The correct option is B different with 2, 1 and 0 lone pairs of electrons respectively

${XeF}_3^{+}$ has $2$ lone pairs

${SF}_3^{+}$ has $1$ lone pairs

${CF}_3^{+}$ has $0$ lone pairs

Because of decreases in no.of lone pairs shape of the molecule changes.
