Explanation In periodic table, electronegativity decreases as we go top to bottom in same group of periodic table because their size generally increases and net attractive force between outermost electrons and nucleus decreases. Electronegativity increases as we move from left to right because size of atoms decrease from left to right, therefore attractive force between outermost electron and nucleus increases. Pauling scale is also used to see the value of electronegativity of elements. Given: a. In modern periodic table, when we go from top to bottom electronegativity decreases because attractive force between outermost electrons and nucleus decreases. As, F, Cl and I belong to 17 t h group of periodic table and F is at the top while I is at the bottom among them. Therefore, order of increasing electronegativity is I < Cl < F b

Plan the synthesis of the following compound using the starting material provided and any other reagents needed as long as carbon based reagents have 3 carbons or less. Either the retrosynthesis or the forward synthesis (mechanisms are not required but will be graded if provided) will be accepted if all necessary reagents and intermediates are shown (solvents and temperature requirements are not needed unless specifically involved in the reaction, i.e. DMSO in the Swem oxidation or heat in the KMnO4 oxidation). There may be more than one correct answer, and chemically correct steps will be accepted. Extra points will be given if correct names are provided.
