Chemical Bonding And Molecular Structure Question 107
Question: The electronic configuration of four elements L, P, Q and R are given in brackets $ L,( 1s^{2},2s^{2},2p^{4} );Q,( 1s^{2},2s^{2},2p^{6},3s^{2}3p^{5} ) $ $ P,( 1s^{2},2s^{2},2p^{6},3s^{1} );R,( 1s^{2},2s^{2},2p^{6},3s^{2} ) $ The formulae of ionic compounds that can be formed between these elements are [NCERT 1983]
Options:
A) $ L_2P,RL,PQ $ and $ R_2Q $
B) $ LP,RL,PQ $ and $ RQ $
C) $ P_2L,RL,PQ $ and $ RQ_2 $
D) $ LP,R_2L,P_2Q $ and $ RQ $
Show Answer
Answer:
Correct Answer: C
Solution:
Valencies of L, Q, P and R is - 2, - 1, + 1 and + 2 respectively so they will form $ P_2L,RL, $
$ PQ $ and $ RQ_2 $ .
