Pick out the isoelectronic structures from the following .
`I CH_3^+ (II) H_3O^+ , (III) NH_3, (IV) CH_3^-` :

A

`CH_3^+`

B

`H_3O^+`

C

`NH_3`

D

`CH_3^-`

Text Solution

Verified by Experts

The correct Answer is:
B,C,D
Total number of electrons in `CH_3^(+)=8`
Total number of electrons in `H_3O^(+), NH_3` and and `CH_3^(-)` are 10 in each case. As such `H_3O^+ , NH_3 and CH_3^(-)` are isoelectrons.
