Final answer:

The characteristic signals in the diagnostic region of an IR spectrum can help identify the functional groups present in a compound. Here are the characteristic signals for each of the compounds.

Step-by-step explanation:

The characteristic signals in the diagnostic region of an IR spectrum can help identify the functional groups present in a compound. Here are the characteristic signals for each of the compounds:

a) 1-methylcyclohexanol: The diagnostic region would show a broad peak around 3300 cm⁻¹, indicating the presence of an alcohol (-OH) group.

b) 4-methylcyclohexene: The diagnostic region would show strong peaks around 1650 cm⁻¹ and 3100 cm⁻¹, indicating the presence of a carbon-carbon double bond (C=C) and sp² hybridized carbon-hydrogen (C-H) bonds.

c) 1-hexyne: The diagnostic region would show a strong peak around 2150 cm⁻¹, indicating the presence of a carbon-carbon triple bond (C≡C).

d) 2-hexyne: The diagnostic region would show a strong peak around 2150 cm⁻¹, indicating the presence of a carbon-carbon triple bond (C≡C).

e) 3-hexyne-2,5-diol: The diagnostic region would show a broad peak around 3300 cm⁻¹, indicating the presence of an alcohol (-OH) group.
