SP2 IO Three outer atoms and one lone pair surround the central atom. The carbon-bromine bonds in the dibromomethane molecule(CH2Br2), for example, are polarised toward the more electronegative value bromine atom, and because all (C-H and C-Br) bonds have the same size and polarity, their sum is non zero due to the CH2Br2 molecules bond dipole moment, and the CH2Br2 molecule is classified as a polar molecule. Complete the octet of the central atom. Write structural formulas for the following: (a) 2,3-Dimethyl-1-cyclobutene (b) 2-Methyl-2-butene CH3NH2.
