Question 1

What is the chemical name of Aspirin?

Accepted Answer

Aspirin is prepared by the acetylation of salicylic acid using acetic anhydride in the presence of an acid catalyst. The chemical name of Aspirin is acetylsalicylic acid (or 2-acetoxybenzoic acid). Answer: acetyl salicylic acid

Question 2

Identify antimicrobial compound from following.

Accepted Answer

Cinnamaldehyde is the main active component of cinnamon oil and is widely recognized in chemistry for its strong antimicrobial properties against various bacteria and fungi. Curcumin is primarily known for its antioxidant properties. Methyl salicylate is an analgesic used for pain relief. Ascorbic acid is Vitamin C, which acts primarily as an antioxidant. Thus, cinnamaldehyde is the antimicrobial compound.

Question 3

Which from following plants is useful to extract analgesic compound from it ?

Accepted Answer

Wintergreen oil contains methyl salicylate, which is widely used as an analgesic compound in various pain-relieving ointments and balms. Turmeric contains curcumin, which is primarily known for its anti-inflammatory and antiseptic properties. Cinnamon contains cinnamaldehyde, used mainly as a flavoring agent and has antimicrobial properties. Citrus fruits are rich in citric acid and vitamin C. Therefore, wintergreen is the plant useful for extracting an analgesic compound. Answer: Wintergreen

Question 4

Which medicinal property is exhibited by methylsalicylate?

Accepted Answer

Methyl salicylate, commonly known as oil of wintergreen, is widely used in medicine as an analgesic. It is applied topically in the form of ointments and liniments to relieve muscle and joint pain. Therefore, it exhibits analgesic properties. Answer: Analgesic

Question 5

Which of the following detergents is used as germicide?

Accepted Answer

Cationic detergents are quaternary ammonium salts of amines with acetates, chlorides, or bromides as anions. They possess germicidal properties and are often used in hair conditioners and other cosmetic products. An example of a cationic detergent is cetyltrimethylammonium bromide. Therefore, cationic detergents are used as germicides. Answer: Cationic detergent

Question 6

Which of the following cleansing agents contains cationic detergent?

Accepted Answer

Cationic detergents are quaternary ammonium salts of amines with acetates, chlorides, or bromides as anions. The cationic part possesses a long hydrocarbon chain and a positive charge on the nitrogen atom. Cetyltrimethylammonium bromide is a popular cationic detergent and is widely used in hair conditioners. Anionic detergents are commonly used in household detergents and toothpaste. Non-ionic detergents are used in liquid dishwashing detergents. Answer: Hair conditioner

Question 7

Identify the term used for drugs that reduce or relieve pain without causing loss of consciousness.

Accepted Answer

Analgesics are neurological active drugs that reduce or abolish pain without causing impairment of consciousness, mental confusion, incoordination or paralysis or some other disturbances of nervous system. Antipyretics are chemical substances which reduce body temperature during high fever. Antibiotics are chemical substances produced wholly or partly by chemical synthesis, which in low concentrations inhibit the growth or destroy microorganisms by intervening in their metabolic processes. Antim

Question 8

Identify the use of Formalin from the followings.

Accepted Answer

Formalin is a 40\% aqueous solution of formaldehyde. It is widely used for the preservation of biological and anatomical specimens because it prevents decay and tissue degradation by cross-linking proteins. Answer: Preservation of biological and anatomical specimens

Question 9

Identify the use of antipyretic drugs.

Accepted Answer

Antipyretic drugs are chemical substances which are used to lower the body temperature in high fever. Common examples of antipyretic drugs include paracetamol and aspirin. Drugs used to kill microorganisms are called antimicrobials or antibiotics. Drugs used to relieve pain are called analgesics. Drugs used to prevent pregnancy are called antifertility drugs. Answer: To reduce fever.

Question 10

What is the result when soap is used in hard water?

Accepted Answer

Hard water contains dissolved calcium and magnesium ions (Ca^ 2+ and Mg^ 2+ ). When soap (which is typically a sodium or potassium salt of a long-chain fatty acid, such as sodium stearate) is added to hard water, these ions react with the soap molecules. The sodium or potassium ions are replaced by calcium and magnesium ions, leading to the formation of insoluble calcium and magnesium salts of the fatty acids. For example: 2C_ 17 H_ 35 COONa + Ca^ 2+ (C_ 17 H_ 35 COO)_2Ca + 2Na^+ These insoluble

Question 11

Which of the following statement about enzyme is correct ?

Accepted Answer

Enzymes are biological catalysts that speed up the rate of biochemical reactions without being consumed in the process. They do not alter the equilibrium constant of a reaction; they only help attain equilibrium faster. They work by lowering the activation energy of the reaction, not increasing it. Enzymes are highly specific in their action, meaning each enzyme typically catalyzes only one specific reaction or acts on a specific substrate. Thus, the statement that they are specific in their act

Question 12

What type of drug the aspirin is?

Accepted Answer

Aspirin (acetylsalicylic acid) is a non-narcotic analgesic. It is widely used to relieve minor aches and pains, and also has antipyretic (fever-reducing) and anti-inflammatory properties. Therefore, aspirin is classified as an analgesic. Answer: Analgesic
