You are watching: Why does water have a higher boiling point than ethanol
(Original short article by smetin92) i think i understand a tiny bit:ethanol is a slightly larger molecule than water, so in a resolved volume, under ethanol molecules have the right to fit into the space, so under H bonds type between the molecules. However, for water, lock are smaller the turning back cn it is in seen. I dont what else to speak in regards to dipoles etc....
the hydrogen bonding between the molecule of water is higher than the bonding between the molecules of ethanol which means more warm energy is required to break the binding of molecule of water which leads to the rise in rememberingsomer.comllision the the water molecules over there by increasing the boil point.
because that water all 3 molecules space able to kind hydrogen bond with adjacent molecules. Ethanol has got 2 carbons, several hydrogen, and also just one oxygen - in laymans term that is huge as youve said. Together you said, that all about the dipole moment of water, i.e. Higher internal power thus waters high particular heat capacity (energy forced to put it increase by 1°C)
(Original post by iceman_jondoe) the hydrogen bonding in between the molecules of water is higher than the bonding between the molecules of ethanol which means more warm energy is required to rest the bond of molecule of water which leads to the boost in rememberingsomer.comllision that the water molecules there by boosting the boiling point.
I perform not understand what you median by the hydrogen bonding is higher? carry out you median there are much more of them, or they are stronger?
water can form two hydrogen bonds as result of there gift 2 delta posotive hydrogens incurred by the electronegative oxygen atom. Water because of this has more permanent-permanent dipole attractions i m sorry take more energy to break 보다 the power required to break the intermolecular bond in ethanol. Hence water has actually a higher boiling point. Expect this helps.
This discussion is eight years old!Anyhoo, to have actually H-bonding, you need an H atom attached to N or O or F. This leader to very polar N-H or O-H or F-H bonds. Leading to a very delta + H atom. This is then attracted to the lone pair on an N or O or F on one more molecule.C is no electronegative sufficient to create a large enough delta H, for this reason can"t form what you would call an H-bond to one more molecule - water or not.
