$SO_3$

Vedclass · Answer

(B) $SO_3$ exists in three allotropic forms:$a$) $\alpha-SO_3$: It forms long,transparent,ice-like crystals. The melting point of this form is $17^{\circ} C$.$b$) $\beta-SO_3$: It forms needle-like,silky white crystals. It melts at $32.5^{\circ} C$. Above $50^{\circ} C$,it changes to the $\alpha$-form.$c$) $\gamma-SO_3$: It is similar to the $\beta$-form and is obtained by completely drying $\beta-SO_3$. It melts at $62.2^{\circ} C$ under $2$ atmospheric pressure.
