Homework Answers
Option A is correct. The IR for terminal Alkyne is at 3500cm-1 ( more correct: 3300-3400cm-1) which is the strongest. Not only will it have maximum energy (as per E=hv) but as per hooks law, more v will have more k which makes the bond more strong.

please answer the following
15. Consider the MAJOR product outcomes when 8 reacts with Nal vs. NaOH. Select the correct outcomes from the table. (Hint 1: for both Sn2 and E2 leaving group must be axial; for E2, the B-hydrogen must be 180° away from leaving group). (Hint 2: For 2 RX substrates, products depend on conjugate acid; i.e.strong acids have weak conj. bases compare to problem #20, 21). 8+ Nal yields products with --- ? 8 + NaOH yields...
