The properties of the resonance X(3872) are discussed under the assumption that this resonance is dominantly a `molecular' JPC=1++ state of neutral D and D^* mesons. It is argued that in these properties should dominate the states with the total spin of the charmed quark-antiquark pair equal to one. As a practical application of this observation the ratio of the rates of the decays X → π0 χcJ for different J is predicted. It is also pointed out that the total rate of these decays is likely to be comparable to that of the observed transitions X → π+ π- Jψ and X → π+ π- π0 Jψ. The decays of the X into light hadrons and its production in hadronic processes are also briefly discussed.
