Crotonaldehyde (CH3 CH = CHCHO)can be easily oxidized to crotonic acid (CH3 CH = CHCOOH) using
KMnO4 oxidise double bond to form diols whereas Triple bond to form Carboxylic acid. Thus tollen reagent is used for the conversion.

For an endothermic reaction, where ΔH represents the enthalpy of the reaction in k.J./mol, the minimum value for the energy of activation will be
In a reaction A → B , the rate of reaction increases two times on increasing the concentration of the reactant four times, then order of reaction is
The rate constant for the reaction, 2N2O5 → 4NO2 + O2 is 3.0 x 10 -5 sec -1. If the rate is 2.40 x 10-5 mol liter-1 sec -1, then the concentration of N2O5 ( in mol liter-1)
