Additional Questions: 15. (a) An alcohol (pka = 15) is reacted with NaNH, (pka = 36). What role does the alcohol play (acid, base, no role)? (b) Draw the reaction of ROH and NaNH2. Use curved arrows to show electron movement R-O-H + O NHA Na slavonotons boi gelts, Part A define NaNH2 as acting as a base and not as a nucleophile? Why do we define 185 or product of the following reaction. What role does the alcohol play?...
Name the type of bonds that each arrow is pointing at. Electronegativity values are: H 2.2, C 2.5, N 3.04, 0 3.4 B C D A. H С N C OH CH HO сн. Bond that arrow A is pointing at: [Select] ionic bond polar covalent bond Bond that arrow B is pointing at: non-polar covalent bond hydrogen bond Bond that arrow C is pointing at: [Select] < Bond that arrow D is pointing at: [Select]
Consider the following reaction: H H-C-0-OH + HN -C-H -T-. A = H-C-0-0 + HN CH HH The arrow is pointing to... neither conjugate acid or conjugate base the conjugate acid the conjugate base
TOT H equation gives the net excess or deficit of hydrogens
relative to the proton reference level. For example: TOT H = [H+] -
[OH-] + [H2CO3*]- [CO32-].
please thoroughly explain

Figure 25.16 (which looks like a horizontal bar with three rows of little blue arrows pointing in the upwards direction through the bar) shows a 100-turn coil of wire of radius 12cm in a 0.15T magnetic field. The coil is rotated 90 degrees in 0.30 s, ending up parallel to the field. What is the average emf induced in the coil as it rotates?
