318877 A face-centred cubic arrangement has \(\mathrm{A}\) and \(B\) atoms. A atoms are at the corners of the unit cell and \(\mathrm{B}\) atoms are at the face centres. One of the \(\mathrm{B}\) atoms is missing from one face center in the unit cell. The formula of the compound is

1 \(\mathrm{AB}\)
2 \(A_{2} B\)
3 \(\mathrm{A}_{2} \mathrm{~B}_{5}\)
4 \(\mathrm{A}_{5} \mathrm{~B}_{2}\)

318878 In a solid AB, atoms " A " occupy the corners and face centre, atoms "B" occupy body centre and edge centre.
If all the face-centred atoms along one of the axes are removed then the resultant stoichiometry of the solid is

1 \({\rm{A}}{{\rm{B}}_{\rm{2}}}\)
2 \({{\rm{A}}_{\rm{2}}}{\rm{B}}\)
3 \({{\rm{A}}_{\rm{4}}}{{\rm{B}}_{\rm{3}}}\)
