Approach to follows, for a compound  International Union of Pure and Applied Chemistry (IUPAC) name prediction

1. First, we find the longest carbon chain.

2. If double or triple bonds are present, the chain must incorporate them.

3. If any double or triple bond is present, we give them the priority while naming the compound, i.e giving them the lowest number.

→ we can see a double in this compound, but the structure is symmetrical, so we can start the numbering from any side.

→ The double bond is present at 2nd position

3. When a double bond is present, we add a suffix $- ene$ to the carbon chain,

Now naming this compound, we get:

2 Butene
