CN CN ek susre ka dipole moment cancle kr denge

what is cn was replaced by oh-?

Non polar :) this was an old jee main q Sp hyb vs sp3

yeah i got that part but ...

polar cus the there is difference bw electronegativity of OH- and CN and they will pull with unequal magnitudes

Ab polar hoga Dono OH ka lone pair opposite side h

In this I get why a and b are non polar

CL Cl ka Dipole moment kaat dega or CN ka bhi same case OH islie Non polar h kyuki jo lone pairs hai wo opposite side lie krege ek dusre ke

why?

For minimum repulsion

Ye ek dusre ko cancle ni kr payega
hardcoreisdead
hardcoreisdeadOP8mo ago
so this is just how the compound is made, to minimize the repulsion as mr makhana said

Yeah

what will be the direction of dipole moment vectors here can you show them in the diagram

Let me try Actually this One is the Trans form but single bond ke about free rotation hota hai to wo cis form me bhi convert hota rehta hai islie net dipole moment kabhi zero ni ata 1 Benzene 1,4 diol ka

My teacher taught this I think it's correct

same goes for the sh one ?

Sulphur me 2 lp hote hai to i think waha pr always hi Dipole moment zero hota hai

hardcoreisdeadOP8mo ago
but thats not the answer...

Yeah my bad the logic that i gave for Benzene 1,4 diol also applies for Benzene 1,4 dithiol due to different conformations or free rotation u can say dipole moment ≠0

hardcoreisdeadOP8mo ago
i hvnt stuided all of this free rotation and stuff so ig ill let it pass for now and remember it like that
Real potato
Real potato8mo ago
Yeah ye isomerism me aayega but yes abhi ke lie aisa samjh sakte ho ki jo lone pairs hai wo ek jagh pr freeze nhi hai they can rotate about their bond

oh damnn, btw can u check the s charac thread once
