Question

Which of the following compounds would you expect to be the most reactive?

A. Ethyne
B. Ethene
C. Methane
D. Ethane

Answer 1

  The   compound  that  would  be   most   reactive  is   Ethyne  (answer A)

     explanation

•    Ethyne   is the  most    unsaturated  among the four  compounds  ( it  has a triple bond between  the two carbon atoms) .

• The  triple  bond in ethyne   is made up  of 1  sigma  bond  and  2π   bond.

• The 2π  bond  are  weaker   and can  easily break   which  make  Ethyne  more  reactive than  Ethene, methane  and Ethane.
