 Hello and welcome to this online course of concept of chemistry for engineering. This is a course we have designed for the first year engineering students for the basic chemistry. Over here now I will give you a description of the full course. So chemistry, maths and physics are the three subjects that has been covered in details in the first year for the engineering students and over here at IIT Bombay we teach two core courses in chemistry. For that we actually teach them physical chemistry, organic chemistry and inorganic chemistry in the form of CH105 and 107 courses. And over there we thought we will design a course for our engineering students who can cater the chemistry related topics from this particular course. And for that we actually devised this 12 week course concept of chemistry for engineering. And this course has been designed such a way that it can help the students to grasp the basic idea which will be very much crucial for their own core courses in the coming years especially the mechanical, civil, chemical, electrical, material science and all the other branches of engineering students. Over here few of the topics that we are going to cover in details are as follows. We will cover over here the basics of quantum chemistry, spectroscopy, thermodynamics, acid base and redox chemistry, the periodic properties, chemical bonding, transition metal chemistry, semiconductors and also the stereochemistry and the basic synthetic organic chemistry. So you can see it is a huge course load that we are going to follow. And that is why we have assembled four faculty members that we are going to teach in this particular course. First of all we have Professor Anindra Dutta from Physical Chemistry. He is a decorated teacher in the Physical Chemistry and Spectroscopy and he is teaching more than 15 years at IIT Bombay. Then we have renowned Professor Devav Brotham Maithi as our inorganic chemistry expert who actually is going to teach you about the basic inorganic chemistry and a little bit about the organometallic chemistry. And then we have Professor Chidambar Kulkarni who is an upcoming faculty in the field of organic chemistry and he expertises in polymer chemistry. So he is going to teach you in the organic chemistry section. And at the end there is also me Anindra Dutta. I am an assistant professor in IIT Bombay where I am going to teach you the inorganic chemistry and the little bit of basics of the physical chemistry. So now we are going to show you what are the course module we are going to follow in this particular course. So you can see first we start in the week one we are going to start with quantum chemistry. This course will be taught by Professor Anindra Dutta where he will be going to he is going to cover Schrodinger equation particle in 1D box and atomic orbitals. And then he is going to bring the next segment quantum chemistry 2 in the coming week where he will build up the things he have taught in the week one. And in this part he will discuss how to develop molecular orbitals, the energy diagrams and pi symmetric orbitals. In the week three we are going to shift our gears and we go to a little bit on the basic inorganic chemistry where Professor Devapathamaiti and I will be teaching you the properties like electronegativity, polarizability, coordination numbers and how we can use this particular concepts to understand the basic geometries formed during the formation of the different molecules. In the week four Professor Devapathamaiti will be covering the first segment of the chemical bonding where he will be teaching the molecular symmetry and how they are connected with respect to the crystal field theory. In the week five Professor Devapathamaiti will be continuing the second segment of the chemical bonding where he will discuss the ligand field theory and the properties of transition metals. And the semiconductors and its properties will be taught by me. Then in the week six Professor Aindrathathamaiti will join back again and he is going to teach the first segment of the spectroscopy where he will cover rotational spectroscopy and vibrational spectroscopy. And next week he is going to continue this discussion where he is going to talk about the optical and fluorescence spectroscopy. The next week we will be covering the NMR spectroscopy and surface characterization techniques. This particular topic will be covered by me. In the last segments of this particular course we will start our discussion on thermodynamics. In the first part of the thermodynamics we will cover all the important parameters like heat energy entropy and how they are connected with redox acid base and solubility equilibria. This part will be covered by me. And then the other segment of the thermodynamics is the different kinds of bonding and the potential energy diagrams will be covered by Professor Chirambar Kulkarni. Then we move to the important factor of stereochemistry where we are going to discuss about the chirality, the enantiomer, the diastereomer and optical activity. And how we can look into a particular molecule and analyze their overall three-dimensional structure. So, this particular segment will be covered by Professor Chirambar Kulkarni and me. And in the last segment we are going to give you some flavor of organic synthesis. How we can build up our knowledge on organic chemistry and take it out for making a bio-relevant compound at the end. So, all the different discussion on the reaction mechanisms with examples will be discussed in this particular segment. And this particular segment will be covered by Professor Chirambar Kulkarni and Professor Devaputamaiti. So, over here you can see we have assembled four different lecturers who are going to cover up different segments from quantum chemistry to spectroscopy which are very much important for understanding the molecular structure of different molecules. Then we are going to discuss also about the thermodynamics aspect. How a system is actually interacting with the surrounding atmosphere. And how we can comment on the different equilibria actually established between a system and surrounding. And in the last segment we are going to discuss about the three-dimensional structures of molecule and how we can learn about the designing of different organic molecules specifically with respect to the drug molecular synthesis. So, with that we believe this will be a very much important course for all the first year engineering students which will establish a strong fundamentals for them that will be very much helpful in the coming days. So, we hope you are going to enjoy this course very much and we look forward to interact with you all through online. Thank you very much.
