Read the passage carefully and answer the Questions
Haloalkanes undergo nucelophilic substitution reactions owing to the polarity of CX bond. The nucleophile reacts with the haloalkane on the carbon possessing a partial positive charge holding the halogen atom. The halogen atom X is replaced by a nucleophile. Depending on the kinetics and mode of bond breaking, the mechanism can be either SN1 or SN2 reaction. The rate of SN1 reaction is governed by the stability of carbocation and in SN2 reaction, the rate of reaction is governed by steric factor. Chirality is the main factor in both SN1and SN2. In SN1 reaction, the chirality of alkyl halide is accompanied by racemization of the product, while in SN2 reaction, the product is characterized by inversion of configuration. The structure of alkyl halide and the nature of the solvent also governs the mechanism of the substitution.
What is meant by the term racemic mixture?

It is difficult to separate the ores of Zr and Hf because:

The value of \(\lambda\) when the projection of \(\vec{a}=\lambda \hat{i}+\hat{j}+2 \sqrt{5} \hat{k}\) on \(\vec{b}=2 \hat{i}+4 \hat{j}+\sqrt{5} \hat{k}\) is 6 , is :

Two events \(E\) and \(F\) are independent. If \(P(E)=0.3, P(E \cup F)=0.5\), then \(P(E / F)-P(F / E)\) equals :

A storage battery of EMF 10 V and internal resistance 1 \( \Omega \) is being charged by a 120 V dc supply using a series resistor of 21 \( \Omega \). What is the terminal voltage of the battery during charging ?

Answer the question on the basis of passage given below :
Formaldehyde is the first member of the aldehydic series. It is present in green leaves of plants where its presence is supposed to be due to the reaction of \(CO_2\) with water in the presence of sunlight and chlorophyll. Commercially, formaldehyde is obtained by the controlled oxidation of methane in the presence of molybdenum oxide (\(MoO\)) acting as a catalyst. Formaldehyde is a constituent of a number of polymers also called resins. These are non volatile solids or semi solids which are obtained directly from certain plants and can be synthesized in the laboratory.
Benzaldehyde is less reactive towards nucleophilic addition reaction than formaldehyde because of:
