Question

Question: Draw the structure for each of the following:

a. 3,3-dimethylcyclopentene

b. 6-bromo-2,3-dimethyl-2-hexene

c. ethyl vinyl ether

d. allyl alcohol

Short answer

Vinylic carbons are the sp²carbons in an alkene and a vinylic hydrogen is a hydrogen bound to a vinylic carbon.

Step-by-step solution

Definition of vinylic hydrogens- 

Vinylic carbons are the sp²carbons in an alkene and a vinylic hydrogen is a hydrogen bound to a vinylic carbon.

Definition of allylic hydrogens-

An allylic carbon is a sp³carbon that is next to a vinylic carbon., whereas an allylic hydrogen is a hydrogen attached to an allylic carbon.

In common names, two groups with a carbon–carbon double bond are used: the vinyl group as well as the allyl group.

The vinyl group is the lowest possible group that contains a vinylic carbon, and it is made up of two atoms.

The allyl group is the smallest conceivable allylic carbon-containing group.

When a substituent is used in a name, it must be connected to the vinylic or allylic carbon, accordingly.
