  1-propanol, CH3CH2CH2OH, b.p. = 82 C
  1-butanol, CH3CH2CH2CH2OH, b.p. = 117.7 C
  1-pentanol, CH3CH2CH2CH2CH2OH, b.p. = 138 C
  1-hexanol, CH3CH2CH2CH2CH2CH2OH,b.p. = 156 C

  The longer the hydrocarbon chain, the higher the b.p. because there are more London dispersion forces between the molecules.

  1-propanol BP 97.1 °C
  this BP was cross-checked with the CRC handbook

  1-butanol BP 117.73 °C,

  1-hexanol BP 151.8 °C
  the CRC handbook has 157.6C
