The compound shown has the molecular formula $C X_{4} H X_{10} O$ . Counting the compound shown itself, how many acyclic structural isomers (alcohols and ethers) have this formula? Ignore stereoisomers.

Answer: D

The compound is butan-1-ol. Acyclic C4H10O isomers: four alcohols (butan-1-ol, butan-2-ol, 2-methylpropan-1-ol, 2-methylpropan-2-ol) and three ethers (1-methoxypropane, 2-methoxypropane and ethoxyethane). Total 4 + 3 = 7 (enumerated by computer).
