Short Answer TypeName the type of isomerism shown by the following pairs of coordination compounds: Â Â
(i) [Co (NH3)NO2Â ]Cl2Â and [Co (NH3)5Â ONO]Cl2
(ii) [Cr (H20)5Â Cl] Cl2Â H2Â O and [Cr (H2Â O)4Â Cl2Â ] Cl.2H20
For the following cell, calculate the emf: Â Â
Al/Al+3Â (0.01M) || Fe+2Â (0.02M)/Fe
Given: E°AI+3/A1 =-1.66 V
E0Fe +2/Fe= -0-44V
An alkyl bromide undergoes reaction in the alkaline medium to form the corresponding alcohol. When the concentration of the alkyl bromide is doubled keeping the concentration of the alkali constant, the rate of the reaction is doubled. When the concentration of the alkali is doubled keeping the concentration of the alkyl bromide constant, the rate of the reaction remains the same.
Write the mechanistic steps for the reaction and state the type of the reaction and the nature of the reagent. Â
Arrange the following in increasing order of acidity and explain your order :
Formic acid, acetic acid, chloroacetic acid
