The correct order of decreasing acidity of the following aliphatic acids is:

Given below are two statements:Statement I: Ferromagnetism is considered as an extreme form of paramagnetism.Statement II: The number of unpaired electrons in a ${\text{Cr}}^{2+}$ ion ($Z=24$) is the same as that of a ${\text{Nd}}^{3+}$ ion ($Z=60$).In the light of the above statements, choose the correct answer from the options given below:

Match List I with List II:List I (Mixture)A. ${\text{CHCl}}_3+{\text{C}}_6{\text{H}}_5{\text{NH}}_2$ B. Crude oil in petroleum industryC. Glycerol from spent-lyeD. Aniline - waterList II (Method of Separation)I. Distillation under reduced pressureII. Steam distillationIII. Fractional distillationIV. Simple distillationChoose the correct answer from the options given below:

For the reaction $\text{A}(\text{g})\rightleftharpoons 2\text{B}(\text{g})$, the backward reaction rate constant is higher than the forward reaction rate constant by a factor of $2500$, at $1000\text{K}$.[Given : $R=0.0831{\text{L atm mol}}^{-1}{\text{K}}^{-1}$ ]$K_p$ for the reaction at $1000\text{K}$ is:

Given below are two statements:Statement I: Benzenediazonium salt is prepared by the reaction of aniline with nitrous acid at $273-278\text{K}$. It decomposes easily in the dry state.Statement II: Insertion of iodine into the benzene ring is difficult and hence iodobenzene is prepared through the reaction of benzenediazonium salt with $\text{KI}$.In the light of the above statements, choose the most appropriate answer from the options given below:
