Question 1: 2,3-butanol CH3CH(OH)CH(OH)CH3 has the delta H vap (kJ/mole) of 72 Given that delta H vap (polar) is 48 what is the dominant

Question 1: 2,3-butanol CH3CH(OH)CH(OH)CH3has the delta H vap (kJ/mole) of 72Given that delta H vap (polar) is 48what is the dominant intermolecular force(s) for the compound? Is it dispersion, polar, or hydrogen bond? Answer may be more than one. Question 2:Why is the Enthalpy of vaporization value of n-pentane at 309.2 K lower than that at 298.15 K? Given that it is 26.200KJ/mol at 298.15 and 25.79 KJ/mol at 309.2. (Multiple choice (one of them is correct))i) The greater volume per mole at the higher temperature indicates greater average intermolecular distances and hence weaker intermolecular forces.ii) The higher temperature indicates greater molecular speed which weakens the intermolecular forces. iii) i and iiiv) None of these
