Question

Draw the structure of a hydrocarbon that has six carbon atoms and

a. three vinylic hydrogens and two allylic hydrogens.

b. three vinylic hydrogens and one allylic hydrogen.

c. three vinylic hydrogens and no allylic hydrogens.

Short answer

The structures of the following are given below.

Step-by-step solution

Definition Allylic and Vinylic carbon

Vinylic Hydrogens are those which are attached to a sp² hybridised carbon atom.

Example: CH₂=CH₂, the 4 H are attached to the sp² hybridised orbital.

Allylic Hydrogens are those which are attached to a Sp³ hybridised orbital.

Example: CH₃CH=CH_2.The H, coloured as Blue are sp³ hybridized. So, they are allylic hydrogens.
