Hydrocarbon saturation
A hydrocarbon (R) has six membered ring in which there is no unsaturation. Two alkyl groups are attached to the ring adjacent to each other. One group has 3 carbon atoms with branching at 1 s t carbon and another has 4 carbon atoms. The larger alkyl group has main chain of three carbon atoms of which second carbon is substituted.We classify the hydrocarbons as saturated and unsatureted on the basis of the number of bonds present between te carbon atoms. For single bonds between the ...
