| Abstract: | There are several chemistry reactions prescribed in the undergraduate syllabi that nearly half the pupil population dread performing (chemophobia), To feel safe and comfortable both physically and psychologically, while working in the laboratories is a legitimate right of every student. The tutors and the instructors share this responsibility. Some green procedures arc being suggested here to establish a doer-friendly atmosphere in the laboratories. The work entails (i) working in meso/micro scale quantities (ii) offmering an alternative chemical/procedure/route for achieving the same results. Two in one economically viable volumetric titrations are proposed which focus on better learning in lesser time. Using the interplay of physical and chemical principles, desired results can be achieved for the preparation of many organic derivatives and often with better yield and purity. Some classical procedures are modified in a green way. Typical organic derivatives have been prepared with minimum energy requirements at ambient temperature avoiding the use of auxiliary substances and avoiding multiple steps in accordance with Green Principles 5, 6 and 8. Two in one derivatives are also prepared for convenience, better quality (even unnecessitating recrystallization) and of-course ill improved yields. Atom economy is critically handled for practical purpose. |
