How many of the following drugs is/are examples(s) of broad-spectrum antibiotics?
Ofloxacin, Penicillin G, Terpineol, Salvarsan.
Ofloxacin, Penicillin G, Terpineol, Salvarsan.
Correct Answer: 1
Solution and Explanation
Ofloxacin is the only broad spectrum antibiotic given in the question
Penicillin – G is a narrow spectrum antibiotic.
Salvarsan is mainly active against spirochete, a bacteria that causes syphilis Terpineol is an antiseptic.
So, the answer is 1.

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.

Concepts Used:
Antibiotics
Antibiotics are a class of drugs used to treat bacterial infections. They work by targeting and killing or inhibiting the growth of bacteria, thus helping the body's immune system to fight off the infection.
Antibiotics can be classified based on their mechanism of action. Some antibiotics, such as penicillin and cephalosporins, interfere with bacterial cell wall synthesis, leading to cell death. Others, such as tetracyclines and macrolides, inhibit bacterial protein synthesis, preventing the bacteria from growing and multiplying. Some antibiotics, such as sulfonamides and trimethoprim, target bacterial metabolism, interfering with the production of essential nutrients and leading to bacterial death.
Antibiotics are commonly prescribed by doctors to treat bacterial infections such as strep throat, pneumonia, and urinary tract infections. However, antibiotics are not effective against viral infections such as the common cold or flu, and their overuse can lead to the development of antibiotic-resistant bacteria. Therefore, antibiotics should only be prescribed when necessary and used according to the prescribed dose and duration.
The discovery of antibiotics has been one of the most significant medical advancements of the 20th century, and antibiotics continue to play a vital role in modern medicine. However, the overuse and misuse of antibiotics have led to the development of antibiotic-resistant bacteria, which pose a significant threat to public health. Therefore, it is important to use antibiotics judiciously to preserve their effectiveness for future generations.
