Ma'am, can you please upload unit 5 of may 2024? I have exam in 4 days...
52:10, what is the answer to that mcq?
You saved me ❤ alhamdulillah
Can you do unit 2 June 2024 please
35:45 isn't the H--O-H bond angle in ice supposed to be 109.5 or 107 becuase oxygen still has a lone pair making it tetrahedral
it has 2 lone pairs which makes the bond angle smaller than 109.5 (tetrahedral) and 107 (trigonal bypiramidal), thus its bent/V shape
My exam went well thanks to your video miss. Thank you
Thank you so much for this May allah reward you and bless you for choosing to take so mich time out of ur life dedicated to making ours easier and for free ❣❣☹☹

20:00 wouldn't it be C(FIVE)
Carbon 1 (both)has 1 neighbouring hydrogen. Carbon 2 has 6 neighbouring hydrogen. Carbon 3 which is a chiral centre has 4 neighbouring hydrogen. carbon 4 has 1 neighbouring hydrogen (which is different from carbon 2 because the environment of carbon 2(6H) and carbon 3(4H) are different themselves, so thats why it has a different environment) Carbon 5 has 4 neighboring hydrogen(same thing that happened to Carbon 4) and carbon 6 has 2 neighboring hydrogen atoms which none of the other have. CARBON 3 and CARBON 2 IS DIFFERENT because CARBON 3 is a chiral centre
Please solve June and Oct 24 papers
Ok
thank you maam
You are the sole reason I am gonna ace my exams doctor!
@@adeebsattar Best wishes always
36:27 how do we know that sulfate ion is smaller?
its the only factor that different so u assume that is larger because the temperature is higher
this paper was comparatively easy right?
rightt i hope the one on thursday is even easier than this
@@jojozk483 bro isn’t it tmrw?
@atwumer IT IS, i pray it is easy good luck guys
