(a) Interpretation: The reason as to why a potassium atom is larger than a sodium atom is to be stated. Concept introduction: The distance present between the nucleus and the valence shell electrons of an atom is known to be the atomic size or atomic radius of that atom. On moving along the period in a periodic table, the number of orbital remains same and a new electron is added to the same orbit. As a result, the atomic radius of elements decreases along the period. On the other hand, the atomic radius of elements increases down the group due to addition of extra orbital.

Question

Propose an efficient synthesis for the following transformation: EN The transformation above can be performed with some reagent or combination of the reagents listed below. Give the necessary reagents in the correct order, as a string of letters (without spaces or punctuation, such as "EBF"). If there is more than one correct solution, provide just one answer. A. t-BuOK B. Na2Cr2O7, H2SO4, H2O C. NBS, heat F. NaCN D. MeOH E. NaOH G. MeONa H. H2O I. 1) O3; 2) DMS
