(c) Only neutron capture occurs (d) Neutron capture and positron emission occurs (e) Electron capture occurs and α particle emission. 2. What set of hybrid orbitals is used by C in ClCN?? (a) sp 2 (b) dsp 3 (c) (d) (e) d 3. Given: 2O 3 (g) ––> 3O 2 (g) rate = k [O 3 ] 2 [O 2 ] –1 The overall order of the reaction is (a) 1 (b) 2 (c) 3 (d) –1 (e) 0 4.
