Question

please help! will rate! white boxes beed to be filled in & Im struggling with questions 1-3 thank you!!

1. Balance the following reaction equation. Note: in Organic Chemistry, a standard balanced reaction equation not only balances all the elements on the left vs. the right, but also shows molecular structures. Formulas such as "C.H.O." are normally not used, because they don't identify a specific isomer. conc. HCI conc. HCI X 2. Complete the following table, using your actual measured amounts. Greyed-out cells do not need to be filled Beaker 01.199 Ratio MW(g/mol) conc.(M) vol. mass mmol equivalents mp (mL) (mg) (°C) 2,5-dimethylhexane- 146.23 2,5-diol 1.279 HCl(aq) 2mL 183.12 2,5-dichloro-2,5- dimethylhexane (crude) -3013 5 662"c 183.12 2,5-dichloro-2,5- dimethylhexane (recrystallized) 1.06g| 65-4686 3. Describe the results of your chemical tests: a) Finkelstein (sodium iodide/acetone) test: Apercipate did not form because there is not a primary. 6) AgNO, test: A pereipate formed within 1 minute allowing me to know that a there is not a primary.
