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 III
C. I and IV
D. II, III and IV.

Answer 1

Correct Answer - D
`overset(+)CH_3=6+3-1=8e^-`
`H_3O^(+)=7+8-1=10e^-`
`NH_3=7+3=10e^-`
`CH_3^-` =12+3+1 =`10e^-`
