please explain in detail. thank you in advance .
Consider the regioselectivity observed in these E2 reactions. Note that product A forms when the base (methoxide ion, CH,0) removes the proton from the carbon labeled B., while product B forms when the base removes the proton from the carbon labeled B2. Why is formation of the less highly substituted (less stable) double bond favored in product B? (1 pt) CHE B CHE A -- Reaction #1 CH, O product A...

(25 marks) In class we discussed the interference pattern produced by eight equally spaced, narrow slits (see powerpoint Ch. 4 pg 31). We used phasor diagrams to show that each of the cases o = 1/4, 1/2, and a gives intensity minimum. We claimed that minima also occur for 0 = 31/4, 51/4, 31/2, and 71/4. Draw the phasor diagram for each of these four cases, and explain why each diagram proves that there is in fact a minimum.
