CHEMISTRY CLASSES BY PRADEEP SHARMA

Students , It is the high time for exam preparations . Lots of students are suffering from exam anxiety . But at this moment only one thin matters i.e. Smart preparations. Following video explains the easiest method for exam preparations.

d Block elements are those in which last electron enters in d subshell . Transition elements are those which possess partially filled d-subshell. Notes - Students can download #Notes of d&F-block from following Link -

Lots of questions in organic chemistry comes from the reasoning section. Each and every chapter of organic chemistry possess large number of reasoning questions. Answer of most of the question is based on resonance and inductive effect. A student must have prior knowledge of resonance and inductive effect to solve all the problems correctly. In case of halo alkanes and halo airings most of the questions comes from reactivity. Answers of all these questions are based upon resonating structure and partial double bond. In case of alcohols and phenols most of the questions are from acidic strength. Again strong knowledge of resonance and resonating structure can help in solving such type of questions. In case of aldehydes and ketones most of the questions are based on reactivity and the answer of these questions are based upon inductive effect. In case of a Amines maximum questions appears from basic strength and the answer in wall both residents as well as inductive effect...
