Question

question 11 (1 point) which formula represents an acyclic alkane? c₉h₁₈ c₁₀h₂₀ c₁₂h₂₆ c₁₂h₂₈ c₁₀h₁₈

Explanation:

Step1: Recall alkane formula

The general formula for acyclic alkanes is $C_nH_{2n + 2}$.

Step2: Check each option

For $C_9H_{18}$, if $n = 9$, $2n+2=2\times9 + 2=20
eq18$.
For $C_{10}H_{20}$, if $n = 10$, $2n + 2=2\times10+2 = 22
eq20$.
For $C_{12}H_{26}$, if $n = 12$, $2n+2=2\times12 + 2=26$.
For $C_{12}H_{28}$, if $n = 12$, $2n+2=2\times12 + 2=26
eq28$.
For $C_{10}H_{18}$, if $n = 10$, $2n+2=2\times10+2 = 22
eq18$.

Answer:

$C_{12}H_{26}$
