whats the general formula for an alkane if n is the number of carbon atoms?
a) cₙh₂ₙ+₂
b) cₙhₙ+₁
c) cₙh₂ₙ+₄
d) cₙhₙ

Explanation:

Alkanes are saturated hydrocarbons with single - bond carbon - carbon and carbon - hydrogen bonds. The general formula for alkanes is derived from the fact that for each carbon atom (except the two terminal ones), there are two hydrogen atoms attached, and the two terminal carbon atoms have an additional hydrogen atom each. Mathematically, if there are \(n\) carbon atoms, the number of hydrogen atoms is \(2n + 2\). So the general formula for an alkane is \(C_{n}H_{2n + 2}\).

Answer:

A) \(C_{n}H_{2n+2}\)
