7.The major product's) in the following reaction is (are) CH,CH CH CH,OH OCH, CH, CH,CH OCH CH,CH [A] Only 1 [B] Only [C] A racemic mixture of [1] and [D] None ofthese a. Which of the following represents the order of solvents in increasing polarity from left to right A) methanol, acetone, ethyl acetate, hexanes B) hexanes, ethyl acetate, acetone, methanol C) acetone, hexanes, methanol, ethyl acetate D) ethyl acetate, methanol, hexanes, acetone 9. In Thin Layer Chromatography (TLC) Re stands for A) Rate factor B) Refractive Index C) Retardation factor D) None of the above 10. Which of the following statements is(are) true? A) If a polar compound moves too slowly in a non-polar solvent, switching to a more polar solvent will cause the compound to move faster B) If a non polar compound moves too fast on a TLC plate switching to a less polar solvent will cause the compound to move slower C) The polarity of a solvent system can be varied by mixing two solvents together D) All of the above 11. An experiment resulted in the generation of approximately 30 mL of organic waste, which is mostly chloroform CHCl. The correct method of disposal of this waste is to: A) Carefully pour it down the sink and subsequently flush with cold water B) Allow it to sit for a while in the fume hood for complete evaporation C) Pouring the material into a waste container designated for halogenated wastes D) None of these

Explanation / Answer

8. option B is the right answer.

hexanes < ethyl acetate < acetone < methanol ( normal alkane < ester < ketone < alcohol)

9. option C is right

retardation factor = Rf = it is the ratio of distance travell by the spot divided by distance travel by solvent

10. option A and C

more polar compound is more soluble in polar solvent and as the solubility increases the movement will faster and polarity of solvent system can vary mixing of different polar solvents
