5b) Rimonabant was the first cannabinoid receptor 1 antagonist. Its structure is shown below. In the boxed structure, draw in all missing lone pairs of electrons. Assume each atom has a formal charge of zero. i. For each arrow (1-6) provide the orbitals used (hybridized or unhybridized) to form each of the indicated bonds (eg, Csp2Csp2,CpCp). Write your answers above. ii. What is the degree of unsaturation of Rimonabant? iii. How many nitrogen atoms in Rimonabant are sp3 hybridized
