1.	The general Formulae of three compund is A,B and C is CnH2n .... B has the highest boiling pt. and c has lowest boiling pt.i-- Mention the type of compound.ii) Which of these has the minimum no. of carbon atoms.iii) Name the homlogous seri to which A,B and C belong.
Answer» 1)since the FORMULA is of $C_nH_{2n}$ so it is a ALKENE is has one C-C double bond i.e. sp² hybridized 2) The BOILING point of Homologues DEPENDS on the molecualr mass i.e. with INCREASE of molecular mass boiling point INCREASES so since compound C has the lowest boiling point so C has the lowest number of carbon atoms 3) Olefins or Alkene
