Open the editor below and draw the skeletal structure, where each atom obeys the octet/duet rule and no atom possesses a formal charge, for the molecule whose condensed structure is below.

(a) (CH3)2CHCHCHC(CH3)3



(b) (CH3)3CC(CH3)2CHCHCH3


Remember for skeletal structures you do not show hydrogens that are bonded to carbon (hydrogens bonded to any other atom must be shown). Also, carbon labels are not used - carbons are understood to be at vertices and at the end of "sticks".
