Riddle # 2 I am a highly effective electron donor, used in organic chemistry. You will find my 3 constituent elements (2 metals & 1 non-metal) in the Ist , II nd and III rd periods of the periodic table. The non-metal one has some properties of alkali metal. In an organic compound having both C = C & carbonyl functional groups, I can selectively change one functional group to a new one. Questions (a) What are my constituent elements ? (b) What is my name and formula ? (c) Which functional group can I change when both double bond and carbonyl groups are present in an organic compound ? (d) What is the new functional group formed ?
