Propose structures for the lettered compounds based upon the data given below.
A =B =C = D = E = F =
An alkane A (C6H14) reacts with chlorine to yield only three compounds (B, C, and D) with the formula C6H13Cl. Of these only C and D undergo dehydrohalogenation with sodium ethoxide in ethanol to produce an alkene. Moreover, C and D yield the same alkene E (C6H12). Treating E with HCl produces a compound F that is isomeric with B, C, and D.
