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),...

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.

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
