Your TA gave you 1 H NMR spectra of your product and iodotyrosine. Using the 1 H NMR spectra and the data given in the special section (p44 and 45), determine the structure of your product - i. E. Do you have ortho-bromo-4-tert-butylphenol, or meta-bromo-4-tert-butylphenol? Explain (using the 1 H NMR) how you came to your decision

Explain which group an element with the electron configuration 1s2 2s2 2p6 3s2 3p6 3d1 4s2 belongs to.

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
