I guess they want the molecular shape and not the structure (in the latter we consider the lp)
So 2nd and 3rd are the only ones I guess
Given ans is 6,could you point out which of these is non planar
Okay they are then asking the molecular shape
Except the first one which has tetrahedral geometry all are planar (wrt molecular shape)
Wait let us confirm @Supreeta_Sen I think they should specify it !
Yeah, you’re right bro
