Q

Why are Alkanes insoluble in water?

A

Alkanes are nonpolar, whereas water in polar, therefore the water molecules do not interact with the alkane molecules

Q

What are the 2 reasons that are Alkanes unreactive?

A
  1. The C-C and C-H bonds have high enthalpy it is relatively difficult to break C-C bonds and C-H bonds
  2. C-C bonds are non polar and C-H bonds are very close in polarity
