HiHere is your answer,
(c) When double and triple bonds are present at equivalent bonds are present at equivalent positions, then preference is given to double bond while numbering the carbon chain. Thus,
1 2 3 4 5 6
CH₂ -- CH - CH₂ - CH₂ - C ≡ CH (-- double bond)
sp² sp² sp³ sp³ sp sp
∴ C₂ - C₃ bond if formed by overlap of sp² and sp³ orbitals.
Hope it helps you !
