(c)The molecular formula C3H4is satisfied by the structures1.38(a)The only atomic arrangements of C3H6O that contain only single bonds must have a ring aspart of their structure.(b)Structures corresponding to C3H6O are possible in noncyclic compounds if they contain acarbon–carbon or carbon–oxygen double bond.1.39The direction of a bond dipole is governed by the electronegativity of the atoms it connects. In eachof the parts to this problem, the more electronegative atom is partially negative and the less elec-tronegative atom is partially positive. Electronegativities of the elements are given in Table 1.2 ofthe text.(a)Chlorine is more electronegative (d)Oxygen is more electronegative than than hydrogen.hydrogen.(b)Chlorine is more electronegative (e)Oxygen is more electronegative than than iodine.either hydrogen or chlorine.(c)Iodine is more electronegative than hydrogen.1.40The direction of a bond dipole is governed by the electronegativity of the atoms involved.
