AIPMT 2009 Preliminary Mock Test

${\text{Al}}_2{\text{O}}_3$ is reduced by electrolysis. If $4.0\times 10^4\text{amperes}$ of current is passed through molten ${\text{Al}}_2{\text{O}}_3$ for $6\text{hours}$, what mass of aluminium is produced? (At. mass of $\text{Al}=27{\text{g mol}}^{-1}$)

Benzene reacts with ${\text{CH}}_3\text{Cl}$ in the presence of anhydrous ${\text{AlCl}}_3$ to form:

Which of the following is not a permissible arrangement of electrons in an atom?

The dissociation constants for acetic acid and $\text{HCN}$ at $25^{\circ }\text{C}$ are $1.5\times 10^{-5}$ and $4.5\times 10^{-10}$ respectively. The equilibrium constant for the equilibrium ${\text{CN}}^{-}+{\text{CH}}_3\text{COOH}\rightleftharpoons \text{HCN}+{\text{CH}}_3{\text{COO}}^{-}$ would be:

Propionic acid with ${\text{Br}}_2/\text{P}$ yields a dibromo product. Its structure would be:
