Hyperconjugation effect comes into existence when a C-H bond is present at Beta-position to a double bond.

Explanation

**Step-by-Step Solution:**

1. **Understanding Hyperconjugation**: Hyperconjugation is an electronic effect that occurs due to the interaction between the electrons of a sigma bond (usually a C-H bond from an alkyl group) and the pi electrons of an adjacent double bond or a vacant p-orbital.

2. **Identifying the Positions**: In the context of hyperconjugation, we refer to the positions of the carbon atoms involved in the double bond. The carbon atom that is part of the double bond is referred to as the alpha (α) position, while the carbon atom that is adjacent to it (which has the C-H bond) is referred to as the beta (β) position.

3. **Example Illustration**: Consider an example like ethylene (CH2=CH2) and its derivative where a methyl group is present, such as CH3-CH=CH2. In this case, the C-H bond of the methyl group (CH3) is at the beta position relative to the double bond (C=C).
