Question

1. Methylene carbene (:CH2) attracts electrons in a pi bondbecause of its: a) lone pair of electrons b) incomplete octet c) positive charge d) bent geometry ---> I know it is either a or b, please explain 2. The oxymercuration-reduction reaction (1. Hg(OAc)2, THF-H2O2. NaBH4) avoids carbocation rearrangements because the positivecharge is: a) delocalized by resonance b) stabilized by the acetate ion c) spread over a 3-centered bond d) given to the mercury 1.

Explanation / Answer

a) delocalized by resonance
Since the net positive charge of1 is being delocalized.... The conformation of2-methylbutane that avoids thisinteraction
