- A-III, B-IV, C-I, D-II
- A-IV, B-III, C-I, D-II
The Correct Option is C
Solution and Explanation
To solve this matching question, we need to associate each item from List-I with the correct option from List-II based on their known chemical reactions and applications. Let's go through each option step by step:
- Benzene sulphonyl chloride is known as the Hinsberg reagent. It is used for the test of amines, particularly to distinguish between primary, secondary, and tertiary amines. Therefore, A matches with III.
- The Hoffmann bromamide reaction is a well-known reaction that converts an amide into an amine with the loss of a carbon atom. This reaction also involves the formation of an isocyanate intermediate. Hence, B matches with IV.
- The Carbylamine reaction is a test for primary amines. It involves the formation of an isocyanate intermediate and produces a foul-smelling compound when primary amines are treated with chloroform and an alcoholic base. So, C matches with I.
- Hoffmann orientation leads to anti-Saytzeff orientation in elimination reactions. This means that the less substituted alkene (less stable) is formed in preference to the more substituted one. Thus, D matches with II.
Based on the above associations, the correct matching is:
- A - III
- B - IV
- C - I
- D - II
Therefore, the correct answer is:

Types of Differential Equations
There are various types of Differential Equation, such as:
Ordinary Differential Equations:
Ordinary Differential Equations is an equation that indicates the relation of having one independent variable x, and one dependent variable y, along with some of its other derivatives.
\(F(\frac{dy}{dt},y,t) = 0\)
Partial Differential Equations:
A partial differential equation is a type, in which the equation carries many unknown variables with their partial derivatives.
Linear Differential Equations:
It is the linear polynomial equation in which derivatives of different variables exist. Linear Partial Differential Equation derivatives are partial and function is dependent on the variable.
Homogeneous Differential Equations:
When the degree of f(x,y) and g(x,y) is the same, it is known to be a homogeneous differential equation.
\(\frac{dy}{dx} = \frac{a_1x + b_1y + c_1}{a_2x + b_2y + c_2}\)
