Give reasons: `S_N1` reactions are accompanied by racemization in optically active alkyl halides.

Which of the following statements pertaining to S_N2 reaction are true 1. The rate of reaction is independent of the concentration of the nu-cleophile 2. The nucleophile attacks carbon on the side of the nucleophile molecule opposite of the group being displaced 3. The reaction proceeds with the simultaneous Bond formation and Bondrupture 4. The partial Racemization of an optically active substance results

Elimination reactions (especially beta -elimination) are as common as the nucleophilic substitution reaction in case of alkyl halides. Specify the reagents used in both cases.

Elimination reactions (especially beta -elimination) are as common as the nucleophilic substitution reaction in case of alkyl halides. Specify the reagents used in both cases.

Give reason,why? Hill reaction is not the true form of light reaction.

Aryl halides are less reactive in nucleophilic substitution reactions.Give one example for nucleophilic substitution reactions of aryl halides.

Discuss nucleophilic substitution reaction S_(N^(2) of alkyl halide.

Wurtz reaction involves the interaction of alkyl halides in dry ether with

Give reasons,why? The movement of ions form endodermis to xylem is an active process.
