Perhaps the best part of this channel is that you reply to every comment. That shows you actually do care for your audience. Great video as always

[@chemistrytutor]

Thank you! I do really appreciate all the feedback and the encouragement. It helps keep me going!

Hi Sir. Just a bit confused on the equation at 44:26, whether it is fully balanced. Great video. Thank you.

[@chemistrytutor]

You're right, the green equation isn't balanced! It needs a 2 in front of the H2O and a 1/2 in front of the O2

[@noellecarter9329]

In terms of physical properties of alkanes, where does that appear on the spec and is it necessary to know them? I haven't come across any questions on solubility or polarity for example

[@chemistrytutor]

The big one is boiling point. Not specific to alkanes but you need to know about larger Molecules having more van der Waals forces. This fits into the Bonding topic and to Fractional Distillation. Solubility can come up in a few places. Most commonly in chemical analysis and spectroscopy, put simply from the point of view of alkanes being non-polar and therefore dissolving non Polar things and being insoluble in water. It can come in more indirectly with ideas about why they are not susceptible to attack by nucleophiles or electrophiles as well

[@zhar9177]

Great Video!! Just got confused by temperature conditions such as At 29:45 is the unit used degree celcius or Kelvin ? Thank You

[@chemistrytutor]

You're right. The temperature for catalytic cracking that I wrote should have been in kelvin! Great spot! It's about 500 degrees Celsius (it's fine to generalise to an approximate temp as different refineries vary slightly)

[@zhar9177]

Do we need to know about vacuum distillation for AQA?

[@chemistrytutor]

Good question, no you do not

[@machacooling]

Is this also for CAIEs As level??

[@chemistrytutor]

Hi, yes, this video will be suitable for any exam board. I teach AQA so I always make sure it covers everything needed for AQA. All exam boards are at least 95% the same though. The main differences between them is not the content they include, but rather how they structure the course, what topics are on each exam and the question style

[@successangelsgroup163]

Thank you so much😀

[@chemistrytutor]

You're very welcome! Glad these videos are useful 😃

[@marigeo24]

So alkanes have weak intermolecular forces and strong intramolecular forces?

[@chemistrytutor]

Correct... and not just alkanes. For any molecule at all the Covalent bonds are always much stronger than the intermolecular forces. Typically at least 10 x stronger

[@joshaa9361]

The cyclo nomenclature was a little bit buzzy for me

[@chemistrytutor]

It does get tricky with cylic Compounds. Good news is you are more likely to be asked to draw them as functional group Isomers of alkenes than you are to name them
