(vii)
Answer

(viii)
Answer

CH₃-CH₂-C(C₆H₁₁)(OH)-CH₂-CH₃

(ix)
Answer

Cyclopentene ring with OH at position 1 and double bond between positions 3 and 4

(x)
Answer

HO-CH₂-CH(C₂H₅)-CH₂-Cl

Explanation

This question tests the ability to convert IUPAC names to structures. For alcohols, identify the parent chain, locate the -OH group position, and add substituents at specified carbons. For ethers, the alkoxy group is attached to the numbered carbon of the alkane. For phenols, substituents are placed on the benzene ring relative to the -OH group at position 1. Cyclic alcohols use the prefix 'cyclo' with the -OH at carbon-1.
