Primary Batteries

Primary batteries, also known as non-rechargeable batteries, are a type of electrochemical cell that converts chemical energy into electrical energy. These batteries are designed for single-use, meaning that once the reaction within the battery is completed, it cannot be reversed or recharged.

Explanation:

Primary batteries operate through a one-time chemical reaction that occurs within the battery. The reaction involves the conversion of chemical compounds into new substances, resulting in the generation of electrical energy. As the reaction progresses, the reactants are consumed, and the battery gradually loses its ability to produce electrical energy.

Once the reaction is complete and the reactants are depleted, the battery becomes "dead" and cannot be used again. This is because the reaction cannot be reversed or recharged in primary batteries. The components of the battery are typically not designed to withstand the reverse reaction or to be replenished with new reactants.

Reversibility and Reusability:

In contrast to primary batteries, secondary batteries, also known as rechargeable batteries, are designed to be reversible and reusable. Secondary batteries can undergo a reversible chemical reaction, allowing them to be recharged by applying an external electrical current that drives the reaction in the opposite direction.

Secondary batteries are constructed with materials and components that can withstand the reverse reaction and can be recharged multiple times. This makes them suitable for applications where the battery needs to be reused, such as in portable electronic devices, electric vehicles, and renewable energy storage systems.

Conclusion:

In summary, the reaction in primary batteries occurs only once, and once the reactants are depleted, the battery becomes dead and cannot be reused. On the other hand, secondary batteries are designed to be reversible and can be recharged multiple times, making them suitable for reuse. Therefore, the correct answer to the given question is option 'A': The reaction occurs only once, and after use over a period of time, the battery becomes dead and cannot be reused again.

Read the passage given below and answer the following questions:Reductive alkylation is the term applied to the process of introducing alkyl groups into ammonia or a primary or secondary amine by means of an aldehyde or ketone in the presence of a reducing agent. The present discussion is limited to those reductive alkylations in which the reducing agent is hydrogen and a catalyst or "nascent" hydrogen, usually from a metalacid combination; most of these reductive alkylations have been carried out with hydrogen and a catalyst. The principal variation excluded is that in which the reducing agent is formic acid or one of its derivatives; this modification is known as the Leuckart reaction. The process of reductive alkylation of ammonia consists in the addition of ammonia to a carbonyl compound and reduction of the addition compound or its dehydration product. The reaction usually is carried out in ethanol solution when the reduction is to be effected catalytically:Since the primary amine is formed in the presence of the aldehyde it may react in the same way as ammonia, yielding an additional compound, a Schiff's base (RCH= NCH2R) and finally, a secondary amine. Similarly, the primary amine may react with the imine, forming an addition product which also is reduced to a secondary amine Finally, the secondary amine may react with either the aldehyde or the imine to give products which are reduced to tertiary amines.Similar reactions may occur when the carbonyl compound employed is a ketone.Q. The reaction of ammonia and its derivatives with aldehydes is called
