  Ethylidene  \E*thyl"i*dene\  (Chem.) 
  An  unsymmetrical,  divalent,  hydrocarbon  radical,  {C2H4} 
  metameric  with  ethylene  but  written  thus  {CH3.CH}  to 
  distinguish  it  from  the  symmetrical  ethylene,  {CH2.CH2}.  Its 
  compounds  are  derived  from  aldehyde.  Formerly  called  also 
  {ethidene}.
