IAS Chemistry Edexcel Unit 2 Ch 2 Q & A Intermolecular Forces - Dr Hanaa Assil

[@oatmilkvanillaicedlatte]

thank you for posting this! tomorrow I have one of my chemistry mocks and this video was really helpful :)

Hi 👋 miss can you just let me know from which years paper did you select All this question for all the questions and answers video

[@drhanaaassil-chemistryteac9433]

From most of the past papers

31:09 i think A will have the lowest boiling point because C is an alkene, rest all are alkanes.. am i wrong??

[@Itsmeh-z1j]

i think she mentioned before that all of them are alkanes, so that means C was a cycloalkane, they have the formula CnH2n. or if it was an alkene it still has less C and less H so less electrons and vanderwaals forces would be lower.

[@Itsmeh-z1j]

i think cycloalkanes also have less contact points so the boiling point would be lower

can u make review vid of bio unit 2 plzzz

miss why does z-hex-3-ene-1-ol not make h bonds with water?

[@Alienokojigaming]

i am also confused about that part . Do you have any idea now why it doesn't ?

[@TalalAlnaimi]

Me too does anyone have an idea..

@@TalalAlnaimi The z-hex-3-ene-1-ol does form hydrogen bonds with water, but due to the larger non-polar part of the molecule it does not interact well with water and is therefore, sparingly soluble, where in the other hand this non-polar part interacts well with the ethanol molecule's non polar part and also forms hydrogen bond with ethanol which makes z-hex-3-ene-1-ol completely miscible with ethanol
