Questions Asked in JEE Main exam
Consider a solution of CO$_2$(g) dissolved in water in a closed container. Which one of the following plots correctly represents variation of $\log$ (partial pressure of CO$_2$ in vapour phase above water) [y-axis] with $\log$ (mole fraction of CO$_2$ in water) [x-axis] at

- A thin convex lens of focal length \( 5 \) cm and a thin concave lens of focal length \( 4 \) cm are combined together (without any gap), and this combination has magnification \( m_1 \) when an object is placed \( 10 \) cm before the convex lens.
Keeping the positions of the convex lens and the object undisturbed, a gap of \( 1 \) cm is introduced between the lenses by moving the concave lens away. This leads to a change in magnification of the total lens system to \( m_2 \).
The value of \( \dfrac{m_1}{m_2} \) is

Concepts Used:
Nomenclature of Organic Compounds
Nomenclature of Organic Compounds can be defined as the systematic approach to name different organic compounds present in the world. In order to avoid some long and tedious common names in the general communication, the officials of the International Union of Pure and Applied Chemistry (IUPAC) have formulated some structured way of naming the organic compounds.
IUPAC Nomenclature:
International Union of Pure and Applied Chemistry (IUPAC) introduced the classical nomenclature for the organic compounds systematically. Some rules were introduced such that every molecule has an individual name for its different structures.
The general skeleton of an IUPAC nomenclature is given as:
Primary prefix + word root + primary suffix + secondary suffix
Guidelines set by IUPAC:
- The Longest Chain Rule
- The Lowest Set of Locants
- Multiple instances of the same substituent
- Naming of different substituents
- The naming of different substituents present at the same positions
- Naming Complex Substituents
