Question

SO$_3$ + H$_2$SO$_4$ $\rightarrow$ X + H$_2$O, Y (Hot, Conc) + C $\rightarrow$ Q + R + Z
Z is a neutral oxide. The shapes of molecules of Q and R respectively are

• A. Linear, Angular
• B. Angular, Pyramidal
• C. Linear, Pyramidal
• D. Angular, Tetrahedral

Hint:

When identifying molecular shapes, focus on the electron cloud around the central atom and apply VSEPR theory.

Answer 1

The Correct Option is A

The given reaction involves the conversion of SO\(_3\) with H\(_2\)SO\(_4\) to form product X, followed by the reaction of Y with C to form Q, R, and Z. The shapes of Q and R are determined by their molecular geometries. In this case, molecule Q exhibits linear geometry while R adopts an angular geometry, as expected for molecules with lone pairs of electrons and different bonding angles.
