AIPMT 2009 Preliminary Mock Test

The values of $\Delta H$ and $\Delta S$ for the reaction $\text{C}(\text{graphite})+{\text{CO}}_2(g)\to 2\text{CO}(g)$ are $170\text{kJ}$ and $170{\text{JK}}^{-1}$ respectively. This reaction will be spontaneous at:

Copper crystallises in a face-centred cubic lattice with a unit cell length of $361\text{pm}$. What is the radius of copper atom in $\text{pm}$?

Predict the product

${\text{H}}_2\text{COH}\cdot {\text{CH}}_2\text{OH}$ (ethylene glycol) on heating with periodic acid gives:

According to $\text{MO}$ theory which of the following lists ranks the nitrogen species in terms of increasing bond order?
