Question

Pick out the isoelectronic structures from the following
`underset (I) CH_3^+ underset (II) (H_3) O^+ underset (III) NH_3 underset (IV) CH_3^-`.
A. I and II
B. I and IV
C. I and III
D. II,III and IV

Answer 1

Correct Answer - D
(d) `CH_3^+ = 6 + 3 - 1 = 8e^-`,
`H_3 O^+ = 3 + 8 - 1 = 10 e^-`
`NH_3 = 7 +3 = 10 e^-, CH_(3)^(-) = 6 + 3 + 1 = 10 e^-`.
