Question

There are how many structures possible for a tetrahedral molecule with a formula of AX3Y?

Answer 1

Some options would have definitely helped in answering this question. I am answering this question based on my knowledge and research. Only 1 structure is possible for a tetrahedral molecule with a formula of AX3Y. I hope that this is the answer that you were looking for and it has come to your help.

Answer 2

There is only one structure feasible for a tetrahedral molecule with such a formula, under the supposition that A is in the center of the tetrahedredon. In this case X and Y are in the vertices of the tetrahedron.

If you draw several figures changing the position of the X's and the Y around the center (A), you will see that all are equivalent.

This is the case of the product CH3Cl, named chloromethane, which, for the same reason given above, does not have isomers.
