1.	Which of the following names is correct for underset(CHO)underset(\|)(C)H_(2)-underset(CHO)underset(\|)(C)H-underset(CHO)underset(\|)(C)H_(2)?
Answer» 3-Formylpentane-1,3-dial 1,2,3-Triformylpropane 2-Formylmethylbutane-1,4-dial Propane-1,2,3-tricarbaldehyde. Solution :`underset("3-Formylpentane-1,5-dial or Propane-1,2,3-tricarbaldehyde")(underset(OHC^(5))underset(\|)overset(4)(C)H_(2)-underset(CHO)underset(\|)overset(3)(C)H-underset(overset(1)(C)HO)underset(\|)overset(2)(C)H_(2))`
