For each species below (i) give the hybridization of the central atoms and (ii) give the shape for the atom in the ion. Provide a brief reason for your selection of shape, 

(a) –CH3                                                            (B) + CH3

aaronq · Answer

you can start this by drawing lewis diagrams, then assigning VSPER $(AX_E)$

aaronq · Answer

i guess you can assume a lone pair to be a ligand (X) for the anion

anonymous · Answer

been trying it and my answer is for first sp3 hyb. and tetrahedral trigonal pyramid
 because 4 electron density areas with one non bonding pair. would i be correct?

aaronq · Answer

yeah, the first one would be $sp^3$ which makes it tetrahedral
