Atomic Structure Question 74
Question: Pick out the isoelectronic structures from the following $ \underset{I}{\mathop{CH_3^{+}}}, $ $ \underset{II}{\mathop{H_3{O^{+}}}}, $ $ \underset{III}{\mathop{NH_3}}, $ $ \underset{IV}{\mathop{CH_3^{-}}}, $
Options:
A) I and II
B) I and IV
C) I and III
D) II, III and IV
Show Answer
Answer:
Correct Answer: D
Solution:
$ CH_3^{+}=6+3-1=8{e^{-}}, $
$ H_3{O^{+}}=3+8-1=10{e^{-}}, $
$ NH_3=7+3=10{e^{-}}, $
$ CH_3^{-}=6+3+1=10{e^{-}} $
