“Role of Applied chemistry in service of man-kind”, elaborate the sentence with suitable examples covered in this course.
Define Optical activity, Specific Rotation & Resolution of racemic mixture also give detailed report on all possible isomers of tartaric acid (with structure).
Give definition of any three properties which depends on number of particles (colligative properties).
Out of one laboratory experiments of applied chemistry, students were asked to synthesize nitrobenzene from benzene. Recognize the type of mechanism of this reaction, write reaction and step wise mechanism for the same.
Elaborate the ‘Nucleophillic Substitution Reactions’ with mechanism involved. All reactions should carefully be covered in mechanism and reactivity of alkyl halides towards particular reaction should be mentioned.
Draw phase diagram of one component system taking example of your choice also elaborate underlying equations and explaination.
State difference between homogenous and heterogenous catalysis, citing different examples.
The enthalpies of formation CO (g), CO2 (g), N2O (g) and N2O4 (g) are − 110, −393, 81 and 9.7 KJ/mol, respectively. Find the value of ΔH for the reaction:N2O4 (g) + 3 CO → N2O (g) + 3 CO2 (g)A first-order reaction takes 23.1 min for 50% completion. Calculate the time required for 75% completion of this reaction.
