Tetradecane (C$_{14}$H$_{30}$) is an alkane found in crude oil. When tetradecane is heated to a high temperature, one molecule of tetradecane decomposes to form one molecule of hexane and three more molecules.
Which of the following could represent this reaction?
C$_{14}$H$_{30}$ $\to$ C$_6$H$_{14}$ + C$_4$H$_8$ + 2C$_2$H$_4$
2 )
C$_{14}$H$_{30}$ $\to$ C$_6$H$_{14}$ + C$_6$H$_{12}$ + C$_2$H$_4$
3 )
C$_{14}$H$_{30}$ $\to$ C$_5$H$_{12}$ + 3C$_3$H$_6$
4 )
C$_{14}$H$_{30}$ $\to$ C$_6$H$_{14}$ + C$_2$H$_6$ + 2C$_3$H$_6$
