Explanation / Answer

Line 1 shows starting material spot.

Line 2 shows starting material + product spots

Line 3 ( recrystalised product ) has same spot as on Line 1 ( starting material) , while Line 4 shows that filtrate has both products and starting material.

This indicates that product crystalisation was not done effectively as we find product spots on filtrate ( line 4)
