Answer:
The right choice is → alkane
Step-by-step explanation:
Alkane, alkene , alkyne, and aldehyde all are organic compounds with different formula.
Alkane has a general formula : CₙH₂ₙ₊₂
Alkene has a general formula : CₙH₂ₙ
Alkyne has a general formula : CₙH₂ₙ₋₂
while, Aldehyde has a -CHO functional group.
in the given example Butane C₄H₁₀ it has the general formula C₄H₂.₍₄₎₊₂
So, the right choice is: → alkane
