Can you provide an example of a 12th class chemistry short question and its answer?
Question: Define electronegativity and explain how it affects the formation of chemical bonds.
Answer: Electronegativity is a measure of the tendency of an atom to attract the shared pair of electrons in a chemical bond towards itself. It depends on factors such as the number of protons in the nucleus and the distance between the nucleus and the outermost electron shell. In general, atoms with higher electronegativity values tend to attract the electrons more strongly, resulting in the formation of polar covalent or ionic bonds. On the other hand, when two atoms have similar electronegativity values, a nonpolar covalent bond is formed, where the shared electrons are evenly distributed.
How can I improve my problem-solving skills for 12th class chemistry short questions?
To improve your problem-solving skills for 12th class chemistry short questions, practice solving a variety of numerical problems regularly. Understand the concepts behind the problems and try to identify the relevant formulas or equations to apply. Break down complex problems into smaller steps and take a systematic approach towards solving them. Additionally, seek help from your teacher or classmates if you encounter any difficulties and actively participate in class discussions and group study sessions.
