(choose chapter or problem)

(a) On the basis of the information in 38, give the likely hybridization ofthe orbital that contains the unshared pair of electrons (responsible for the negative charge) in each of the following species: CH3CH2 2; CH2CH2; HCC2. (b) Electrons in sp, sp2, and sp3 orbitals do not have identical energies. Because the 2s orbital is lower in energy than a 2p,the more s character a hybrid orbital has, the lower its energy will be. Therefore the sp3 (14s and34p in character) is highest in energy, and the sp (12s, 12p) lowest. Use this information to determinethe relative abilities of the three anions in (a) to accommodate the negative charge. (c) Thestrength of an acid HA is related to the ability of its conjugate base A2 to accommodate negativecharge. In other words, the ionization HA H1 1 A2 is favored for a more stable A2.Although CH3CH3, CH2CH2, and HCCH are all weak acids, they are not equally so. On thebasis of your answer to (b), rank them in order of acid strength.
