A) \[{{A}_{2}}{{(B{{C}_{3}})}^{2}}\]
B) \[{{A}_{3}}{{(B{{C}_{4}})}^{2}}\]
C) \[{{A}_{3}}{{({{B}_{4}}C)}_{2}}\]
D) \[AB{{C}_{2}}\]
Correct Answer: B
Solution :
In \[{{A}_{3}}{{(B{{C}_{4}})}^{2}}\] \[3\times O.N.\,of\,A+2\,[O.N.\,of\,B+4\times O.N.\,of\,C]=0\] \[3\times (-2)+2\,[+5+4\,\times (-2)]=0\] \[+6+2\,[-3]=0\] Hence, in the compounds \[{{A}_{3}}{{(B{{C}_{4}})}_{2}},\] the oxidation number of A, B and C are +2, +5 and ?2 respectively.You need to login to perform this action.
