The electronic configuration ofhte elements. A, B and C are given below. Answer the question from 14 to 17 on the basis of these configuration.
`{:(A,1s^(2),2s^(2),2p^(6),,),(B,1s^(2),2s^(2),2p^(6),3s^(2),3p^(3)),(C,1s^(2),2s^(2),2p^(6),3s^(2),3p^(5)):}`
The molecular formula of the compound formed from B and C will be

A

BC

B

`B_(2) C`

C

`BC_(2)`

D

`BC_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
B represent P and C represents Cl . The stable compound formed is `PCl_(3) `, .i.e. `BC_(3)`.
