why would the circled protons on the left be diasteriotopic and the circled protons on the right be identical. i dont see the difference. PLEASE thoroughly explain
from an aldehyde or ketone. 3. Suggest reagents that could be used to prepare (2 methods)
Which reagents would you use to convert the aldehyde to the alcohol shown? Thank You!! Which reagents would you use to convert the aldehyde to the alcohol shown? H2. Pd/C NaBH4 in MeOH 1. CH3Li and H307 1. CH3Li in THF 2. H30+ 1. LIAIH4 2. H30+
If you reduce a compound containing an aldehyde, what qualitative test would you use to determine if the product is good or bad?
If you oxidized a compound containing an aldehyde, what qualitative test would you use to determine if the product is good or bad?
Problem #4 Draw the substitution product from each of the following reactions. 1. BH2-THF HgSO4 =CH 2. H2O2, NaOH H2SO4 H2O
How would you combine reactions A-C, shown below, to obtain the overall reaction: NH, () +BH2(g)+0,(3) —> 2H,0(g) +HBNH(s) Please select all that apply. 24,(g) +0,(g) → 24,0(3) H BNHz() NH3(g) +BH3(g) HBNH,(s) -> 2H, (g) + HBNH(s) Choose one or more: A multiply A by 2 B. add resulting equations together C. multiply C by 2 D. reverse A E. divide A by 2 E multiply B by 2 G divide B by 2 H. divide C by 2...
What aldehyde or ketone is needed to prepare the following compound by an Aldol reaction?
Please answer the circled questions. that would be the huge favor. thanks ) From the perspective of operation complexity (bigo), explain why a min-heap is superior to a sorted array for maintaining and providing the minimum weights for building the Huffman tree: Variable-length codes will generate a superior compression ratio vs. fixed-length codes only if the characters in the file exhibit which characteristic? What is the minimum count of bits required for each fixed-length codeword for an alphabet consisting alphabet?...
