For 1-methoxy-1,3-butadiene, which of the following resonating structure is the least stable?
A solid has a structure in which, atoms of W, O and Na are located respectively at the corners, centre of the edge and at the centre of the cubic lattice. Name the compound.
There is one sodium atom in the cube centre, completely within the unit cell. Therefore, the empirical formula of this compound is $$NaWO_3$$.
