Re: IIT Organic Chemistry Questions

As you are looking for IIT Organic Chemistry question papers so here I am sharing with you.

The correct order of acidic character is
(A) Al2O3 > MgO > SiO2 > P4O10
(B) P4O10 > Al2O3 > MgO > SiO2
(C) P4O10 > SiO2 > Al2O3 > MgO
(D) SiO2 > P4O10 > Al2O3 > MgO

The pair of amphoteric oxides is
(A) VO, Cr2O3
(B) V2O3, Cr2O3
(C) VO2, Cr2O3
(D) V2O5, CrO3

In the structure of B4O5(OH) −
(A) all four B atoms are trigonal planar
(B) one B atom is tetrahedral and the other three are trigonal planar
(C) three B atoms are tetrahedral and one is trigonal planar
(D) two B atoms are tetrahedral and the other two are trigonal planar
