In soap manufacturing, the triglycerides present in oils and fats are hydrolyzed to mainly produce
Show Hint
- Fatty acids and glycerol
- Glycerol only
- Fatty acids only
- Glycerol and paraffins
The Correct Option is A
Solution and Explanation
Step 1: Hydrolysis of Triglycerides
Triglycerides react with sodium hydroxide (NaOH) or potassium hydroxide (KOH) in a reaction known as saponification. This results in the formation of fatty acids and glycerol.
Step 2: Conclusion
The main products of this reaction are fatty acids (which combine with sodium or potassium to form soap) and glycerol.
Final Answer: \[ \boxed{\text{Fatty acids and glycerol.}} \]

- The rate of a reaction \( A \rightarrow B \) is \( 0.2 \, \text{mol} \, \text{m}^{-3} \, \text{s}^{-1} \) at a particular concentration \( C_{A1} \). The rate constant of the reaction at a given temperature is \( 0.1 \, \text{m}^3 \, \text{mol}^{-1} \, \text{s}^{-1} \). If the reactant concentration is increased to \( 10 \, C_{A1} \) at the same temperature, the reaction rate, in \( \text{mol} \, \text{m}^{-3} \, \text{s}^{-1} \), is:

Questions Asked in GATE CH exam
An ideal monoatomic gas is contained inside a cylinder-piston assembly connected to a Hookean spring as shown in the figure. The piston is frictionless and massless. The spring constant is 10 kN/m. At the initial equilibrium state (shown in the figure), the spring is unstretched. The gas is expanded reversibly by adding 362.5 J of heat. At the final equilibrium state, the piston presses against the stoppers. Neglecting the heat loss to the surroundings, the final equilibrium temperature of the gas is __________ K (rounded off to the nearest integer).
