Chemguide: Support for CIE A level Chemistry
Learning outcome 3.3(a)
This statement deals with hydrogen bonding.
Before you go on, you should find and read the statement in your copy of the syllabus.
You can't understand hydrogen bonding unless you first understand the concept of electronegativity. If you haven't already done so, you need to read learning outcome 3.3(b) before you go any further with this page. CIE have written these statements in an illogical order!
Read this page on hydrogen bonding.
Near the top of the page, you will find a mention of van der Waals forces, and a link to find out more about them. van der Waals forces are coming up soon in learning outcome 3.3(d), but you won't understand the hydrogen bonding page without having a reasonable idea what van der Waals forces are.
There are two ways you could do this:
Whichever order you do it in, though, you must sort out the electronegativity work first.
