These two poems illustrate the same meaning, the values which help individuals lead peaceful lives. At first, kindness towards others was the plan of humankind in the early decades. They were happy and showed a better life throughout those periods. But in today's generation, the situation has changed drastically. Selfishness has destroyed love and kindness in humankind, leading to the loss of human virtues and values. Therefore, as mentioned in the poem, the selfish motives and personal gain of the new generation must be protected by teaching virtues such as pity, mercy, peace, and love in young people's hearts, making a way to a better life.
A compound (A) with molecular formula $C_4H_9I$ which is a primary alkyl halide, reacts with alcoholic KOH to give compound (B). Compound (B) reacts with HI to give (C) which is an isomer of (A). When (A) reacts with Na metal in the presence of dry ether, it gives a compound (D), C8H18, which is different from the compound formed when n-butyl iodide reacts with sodium. Write the structures of A, (B), (C) and (D) when (A) reacts with alcoholic KOH.
