Final answer:
A carbon-carbon double bond with hydrogen atoms on the same side is a cis double bond, which affects the molecule's shape, creating a bent structure.
Step-by-step explanation:
A carbon-carbon double bond in which the hydrogen atoms are positioned on the same side of the double bond is known as a cis double bond. This type of double bond creates a bent or kinked structure in the molecule because the hydrogen atoms are on the same side and repel one another, affecting the overall shape of the molecule. This is in contrast to a trans double bond, where the hydrogen atoms are positioned on opposite sides of the double bond, leading to a more linear structure of the molecule.
