A student use the same protocol as in the lab manual to extract 4 chloroanilline, benzoic acid and naphthalene. Below are the steps he took Step 1 - Dissolve all three in 15 ml ether and place in separatory funnel Step 2- Add 15 ml of hydrochloric acid and mix well Step 3 - Isolate the aqueous layer and add sodium hydroxide which resulted in a precipitate Step 4- Add 15 ml of sodium carbonate to the ether layer and mix Step 5- Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate. Step 6- dry the ether layer and collect the solid that is left
Thank you, question and choices are in the picture provided.
The following sentence has the format “Statement 1 BECAUSE Statement 2”. Decide whether statement 1 is true, whether statement 2 is true, and whether the REASONING (the ‘BECAUSE’ relationship) between them is valid. Statement 1 − “Cyclohexane-1,2-diol elutes from a silica gel chromatography column after cyclohexane-1,2-dione” BECAUSE Statement 2 − “Ketones stick better to silica than alcohols because the C=O group has a larger dipole than the C-OH group.” Question 6 options: A Statement 1 and Statement 2 are both correct, and the reasoning is valid. B Statement 1 and Statement 2 are both correct, but the reasoning is NOT valid. C Statement 1 is correct, but Statement 2 is NOT correct. D Statement 1 is NOT correct, but Statement 2 is correct. E Statement 1 and Statement 2 are both NOT correct
