CHMB41H3 Lecture Notes - Lecture 18: Bromine, Pi Bond, Rhodopsin
Document Summary
Alkenes suffix ene is what is used to name these compounds: they have a degree of unsaturation. Related to a saturated hydrocarbons (alkanes) they have fewer number of h atoms. Slide 15 you look to see if it is monovalent, divalent or trivalent. Monovalent atom is connected with one single bond: h is also monovalent. Oxygen is divalent: so 2 bonds, you take out the oxygen and connect them. Nitrogen is trivalent: you take nitrogen with a h atom, so you subtract one h from formula. Degree of saturation does not tell us anything about the structure in terms of being a ring or branched i-clicker. 3 bromo 4 chloro 1 bentene i-clicker. 3 electron groups make 3 hybrid orbitals => sp2: 1 s and 2 p => 3 sp2 orbitals. 2 sp2 orbitals make the stigma bond. 2 unhybridized p orbitals make the pi bond. Here we cant rotate because of the double bond.
