Notes are available for the class 11 chemistry (FSc). Topic wise Video lectures for chapter 1 are available here according to each topic.
Class 11 chemistry (1st-year chemistry) is one of the most crucial subjects in FSc class. Premium video lectures are public for FREE. Take advantage and share with others and achieve success in your life. Video Lectures are given below and short question notes are given here.
Lecture 1: Introduction to Atom (Define Atom of Element) FSc 1st year Chemistry Book 1.
This lecture describes the atom, its definition and its historical perspective.
Lecture 2: Evidence of the existence of Atom | FSc 1st year Chemistry book 1
This video is showing you a very good description that proves the existence of atoms. However it is not possible to see the atom through the naked eye but an electron microscope and spectrometer are very important instruments that show, how atoms can be seen.
Lecture 3: Molecule | Molecule and its types | FSc 1st year Chemistry book 1
This video shows a short and conceptual description of molecules and their types.
Lecture 4: Ion | what is ion in chemistry | FSc 1st year Chemistry book 1 | Class 11
This video shows what is ion and the definition of an ion. The species which have some charge on it due to the gain or loss of electron or some kind of irradiation is called ion.
Lecture 5: Relative Atomic Mass | FSc 1st year Chemistry book 1 | Class 11
This video shows what is relative atomic mass. How relative Atomic mass is determined and how an element is compared with standard 1/12th mass of C which is taken as 12
Lecture 6: Isotopes and their relative abundance | FSc 1st year Chemistry book 1
It is a very comprehensive video on isotopes. It makes an idea clear about the isotopes that why they are, how they can be defined and why isotopes have different masses.
Lecture 7: Mass Spectrometer | Spectrometery | Determine Relative Atomic Mass | FSc Class11 Book 1
This is very outstanding lecture on spectrometry. In this video, I will show you how to use a spectrometer to determine the average atomic mass of different isotopes of an element.
Lecture 8: Average Atomic Mass | Determine %age composition of Elements in compound | Chemistry Book 1
In this video, you will learn about what is average atomic mass and how it can be determined. In this way, you can find out the percentage composition of an element in a compound by doing quantitative analysis.
Lecture 9: Empirical formula | How to Determine Empirical formula | Chemistry Book 1
This lecture video shows how to determine empirical formula in chemistry. The empirical formula is very important for determining the molecular formula, so we have to first know about the empirical formula. There are some key points to determine the empirical formula and there is some quantitative and qualitative analysis also involved.
Really a good work …
Very helpful 👍
Sr need excercise solution for both part
1st year and second year
InshaAllah, I’ve a plan to do massive things for my students. Just keep in touch
Thank you sr
Sir thank you so much
