Hydrogen bonding is responsible for: Select the correct answer below:a. the unexpectedly high boiling points for binary molecular hydrides (XHn) in period two b. the increasing boiling points for binary molecular hydrides (XHn) going down a group c. the low boiling points of nonpolar molecules d. none of the above

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

What is the value of the standard enthalpy of formation of an element in its most stable form?
