Why Ice (less dense) floats over Water and Density of Water is maximum at 4°C

Chemical bonding and molecular structure class 11 jee neet study material pdf download free

Anand Classes explains why ice, being less dense, floats over water and why the density of water is maximum at 4°C, based on the concept of hydrogen bonding and molecular arrangement. Students will learn how the open hexagonal structure of ice formed by extensive hydrogen bonding makes it less dense than liquid water. The lesson also covers how, upon cooling, the density of water first increases and then decreases after 4°C, making 4°C the temperature of maximum density. This topic is essential for understanding anomalous behavior of water in Class 11, Class 12, JEE, and NEET Chemistry, and is supported with diagrams, solved examples, MCQs, Q&A, Assertion Reason, and Case Study questions.

Hydrogen Bonding Effects on Boiling Point, Solubility, Volatility, Association, Physical State

Chemical bonding and molecular structure class 11 jee neet study material pdf download free

Anand Classes explains the Effects of Hydrogen Bonding on Boiling Point, Solubility, Volatility, Association, and Physical State of different compounds. Students will learn how intermolecular hydrogen bonding increases molecular attraction, leading to higher boiling points, greater solubility in polar solvents, and lower volatility, while intramolecular hydrogen bonding often reduces solubility and affects the physical state of substances. The topic also discusses how hydrogen bonding causes association in liquids like water and hydrogen fluoride. This concept is important for Class 11, Class 12, JEE, and NEET Chemistry, and is supported with diagrams, examples, MCQs, Q&A, Assertion Reason, and Case Study questions.
