Dipole moment doubt
How should I approach these type of questions .. I thought hbr will be more polar than H2S cuz of electronegativity but it isn't the case .. am I missing something?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.dipole moment is a vector quantity which requires you to know the structure of the compound to calculate
that's why the dipole moment of CCl4 is zero despite the individual C-Cl bond having a nonzero dipole moment
the vector goes from the more electropositive atom to the more electronegative atom
the vectorial sum of all those vectors gives you the overall dipole moment of a molecule
What's the order according to u @Nimboi ?
not entirely sure
i'm also surprised that HBr is less than H2S
but i guess its because Br probably isnt as electronegative as the rest of the halogens
and also H2S has a bent shape
so the resultant dipole vector from each of the 2 bonds probably is more than HBr
for the rest
idk its a weird question
hard to compare
vector sum is more in H2S as 2 hydrogen to 1 sulphur
just see vecotr sum
thats what i did
i see and for comparing chcl3 and h2s .. ig charge and distance should be provided too right?
we can draw structure and figure out for this also
just draw a vector from less EN to more EN
for each structure
and onservereve where the vector sum is more
