Given reactions are the preparation method of alcohol, Find out X, Y, Z in the reaction? ROH+X→R−Cl+SO2+HCl ROH+Y→R−Cl+POCl3+HCl ROH+Z→R−Cl+H3PO3
Assertion (A) . The direction ratios of the line joining origin and point (x,y,z) must be x,y,z
Reason (R): lf P(x,y,z) is a point in space and |OP|=r, then the direction cosines of OP are xr , yr , zr
