\[L\left( 1{{s}^{2}},\text{ }2{{s}^{2}}\,2{{p}^{4}} \right);\text{ }Q\left( 1{{s}^{2}},\,\,2{{s}^{2}}\,\,2{{p}^{6}},\text{ }3{{s}^{2}}\,3{{p}^{5}} \right)\] |
\[P\left( 1{{s}^{2}},\text{ }2{{s}^{2}}\,\,2{{p}^{6}},\text{ }3{{s}^{1}} \right);\,\,R\left( 1{{s}^{2}},2{{s}^{2}}\,\,2{{p}^{6}},\text{ }3{{s}^{2}} \right)\] |
The formulae of ionic compounds that can be formed between these elements are |
A) \[{{L}_{2}}P,\,\,RL,\,\,PQ\,\,and\,\,{{R}_{2}}Q\]
B) LP, RL, PQ and RQ
C) \[{{P}_{2}}L,\,\,RL,\,\,PQ\,\,and\,\,R{{Q}_{2}}\]
D) \[LP,\,\,{{R}_{2}}L,\,\,{{P}_{2}}Q\,\,and\,\,RQ\]
Correct Answer: C
Solution :
Valencies of L, Q, P and R is -2, -1, +1 and +2 respectively so they will form\[{{P}_{2}}L,\,\,RL,\,\,PQ\,\,\,and\,\,R{{Q}_{\text{2}}}\].You need to login to perform this action.
