Question

Given below are two statements:

Statement I: The number of species among ${SF}_{4}$, ${NH}_{4}^{+},\ \left\lbrack {NiCl}_{4} \right\rbrack,\ {XeF}_{4},\ \left\lbrack {PtCl}_{4} \right\rbrack^{2 -},\ {SeF}_{4}\ $ and $\left\lbrack Ni(CN)_{4} \right\rbrack^{2 -}$, that have tetrahedral geometry is 3 .

Statement II: In the set $\left\lbrack {NO}_{2},{BeH}_{2},{BF}_{3},{AIC1}_{3} \right\rbrack$, all the molecules have incomplete octet around central atom. In the light of the above statements, choose the correct answer from the options given below:

Options

A.Statement I is true but Statement II is false
B.Both Statement I and Statement II are false
C.Statement I is false but Statement II is true
D.Both Statement I and Statement II are true

Solution

Statement-I

${SF}_{4}$ (See-saw)

${XeF}_{4}$ (square planar),

$\left\lbrack {PtCl}_{4} \right\rbrack^{2 -}$ (square planar),

[ $\left. \ {NiCl}_{4} \right\rbrack^{2 -}$ (Tetrahedral),

$\left\lbrack Ni(CN)_{4} \right\rbrack^{2 -}$ (square planar),

${SeF}_{4}$ (See-saw)

${NH}_{4}^{+}$(Tetrahedral)

Statement-II

${NO}_{2}$ (seven electrons on N )

${BeH}_{2}$ (four electrons on Be )

${BF}_{3}$ (six electrons on B )

${AlCl}_{3}$ (six electrons on Al )
