Question

Can you tell me which of the following questions are Ture/False

True or false? Indicate your answer simply with T or F. No explanations required. At a lower NMR spectrometer operating frequency, the leaning in AB systems will be stronger. In a X_2CH_A-CH_B Y_2 fragment, the most stable conformation will generate a small ^3J_AB value. Short reaction times at low temperatures favour the fastest-forming product. In enolatealkylations, one equiv. of strong base is preferred to avoid over-alkylation. In enolateacylations, a non-nucleophilic base is preferred to avoid side-reactions. Using enamines in alkylation avoids regioisomers. Intramolecular reactions are innately slower than intermolecular equivalents. Magnetic inequivalence occurs in 4-spin systems when the 4 spins occur in two pairs of two. beta-Eliminations can only proceed under basic conditions. Direct alkylations of low-pK_acarbanions take place readily because metal-halogen exchanges will not occur in those cases.
