    (a) Write the IUPAC name of (i) \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\mathop{C}}\,=CHCOOC{{H}_{3}}\] (ii) (b) Out of     and    which will be eluted first in moderately polar solvent and why?

    Answer:

                    (a) (i) Methyl 3-chlorobut-2-en-1-oate (ii) 3-Methylcyclohexyne (b)  has significant dipole moment while  being symmetrical has zero dipole moment. Therefore, di-tert-butyl benzene is non-polar and hence will not be adsorbed strongly on the adsorbent and hence it will be eluted first in moderately polar solvent.
