O A. The position of the double bond
B. The position of the carbon-hydrogen bond
C. The position of the carbon-carbon single bond
D. The position of the triple bond

Answer 1

Answer: a , the position of the double bond

Answer 2

The position of the double bond. Hence, option A is correct.

What is a carbon-hydrogen bond?

In chemistry, the carbon-hydrogen bond (C−H bond) is a chemical bond between carbon and hydrogen atoms that can be found in many organic compounds.

Alkenes are named by adding the -ene suffix to the prefix associated with the number of carbon atoms present in the molecule.

A number and dash before the name denote the number of the carbon atom in the chain that begins the double bond.

Hence, option A is correct.
