Compound “A” (C6H14) gives three different monochlorides when subjected to photochemical chlorination. One of these monochlorides gives no reaction when treated with KOH/alcohol. The other two monochlorides yield the same alkene “B” when treated with potassium tert-butoxide in tert-butyl alcohol. Give the structural formulas for compound “A”, the three monochlorides, and compound “B”. Show all equations and reactions.
