This relates to an organic chemistry experiment on the synthesis of trans-9-(2-phenylethenyl)anthracene. "Wittig reaction usually requires use of very strong bases for the deprotonation step. Name and give the formula of the strong base learned that could be used for the deprotonation." Please be detailed, thank you.
This relates to an organic chemistry experiment on the synthesis of trans-9-(2-phenylethenyl)anthracene. "In the experiment the substrate was deprotonated with a relatively mild base, NaOH. Explain why this substrate can do this. (hint: ARIO!)" Please be detailed.

Organic chemistry, trans-9-(2phenylethenyl)anthracene synthesis via Wittig Reaction. "Does the H-NMR data suggest this a symmetrical molecule? Does the C-13 NMR data suggest it is symmetrical?" Please be detailed, thank you. Below is the data provided: Compound 21c: (67%); mp 131 °C; IR Vmax (KBr) 3024 cm'' (=CH), 1621 cm'(C=C); UV Nmax (CH3CN) 270 (€ 19,800), 300 (€ 7,900), 350 (€ 1,100), 390 (€ 60,000); 'H NMR (CDC13) 8 6.95 (1H, d, Jax = 16.56 Hz, vinylic), 7.25-8.41 (14H, m, aromatic),...
How would I interpret this 1H-NMR of trans-9-(2-phenylethenyl)anthracene (C22H16)? integration values from left to right are 1.00, 0.66, 3.13, .31, .25 1Η ΤΗ 14 13 12 11 10 -1 Chemical Shift (ppm)
Based on the Wittig Reaction exp. below, please answer a) and b). In b) you can disregard the part about the IR, just please interpret and assign protons, shift values, which protons are for which groups, etc on the HNMR. The % yield was 34%, and MP was lower than expected (to assist with answering part a). This should be all the information you need to answer the question. HNMR Discuss the percentage yield of the reaction. Explain and provide...
Synthesis is a major area of organic chemistry which often requires multiple material to a target compound. A systematic way to propose a synthesis e chemistry which often requires multiple steps to convert one organic systematic way to propose a synthesis is to work backwards from the target compound to a readily available starting material. This 'retrosynthesis app arrow wie starting material. This 'retrosynthesis' approach is indicated by the within a synthesis proposal. (See Wade textbook, pg 410ff, Problem Solving...
