Answer:
1-<u>Pentanol </u>has the highest boiling point.
Explanation:
Boiling points of given compounds are as follow,
1) 2-Pentanone = 101 °C
2) 1-Pentanol = 138 °C
3) Pentane = 36.1 °C
4) Pentanal = 103 °C
Pentanol has greatest boiling point as compare to others because it involes a strongest intermolecular interactions called as hydrogen bond interactions. Remaining compounds lack the direct attachement of hydrogen to most electrnegative atom like oxygen which is present in 1-Pentanol.
According to Dalton's Law, in a mixture of non-reacting gasses, thetotal pressure<span> exerted is the sum of the </span>partial pressures<span> of the component gasses. In more complicated circumstances, equilibrium states come into effect, but fortunately for us, </span>oxygen<span> is non-reactive with </span>water vapor<span>.</span>
<span>Answer – We are given, 2H2+O2 ----> 2H2O , deltaH = -48.4 kJ Moles of H2 =1.8 moles From the above given balanced equation We know, 2 moles of H2 = -48.4 kJ So, 1.8 moles of H2 = ? kJ = 1.8 moles of H2 X -48.4 kJ / 2 moles of H2 =-43.6 kJ So, when 1.8 mol of H2...</span>
