is it ok if we write that introduction of alkane grp gives more reactive products

hey welcome bk....hws studiez goin??

 

[angelgirl:)]

can someone explain hybridisation?

isnt it bio..topic?

no thats wrong, as a matter of fact alkene is more reactive because it has a pi bond present which breaks much easily compared to a sigma bond. so just stick to more useful hydro carbons

ohhh God dont ask...iam lost ...

 

[Hassi123]

no. its in chemistry! its something about sp3 and sp4, i dont get it

 

[saudha]

wht does aldehyde/ketone give in reaction to DNPH

yes thanks...

really? i hav never heard of it in chem...

...there is a particuler reaction with ketone in the txt bk...see it den u will get it

 

[angelgirl:)]

ketone gives but aldehyde dont ...there is a particuler reaction with ketone in the txt bk...see it den u will get it

ohhhh sorry both gives

 

[angelgirl:)]

ohhhh sorry both gives

but see the reaction in the txt bk

 

[Hassi123]

ketone gives but aldehyde dont ...there is a particuler reaction with ketone in the txt bk...see it den u will get it

theres a reaction with both actually ill try sending it wait

i know by mistake i wrote...i was giving view about tholens and fehlings reagent...

 

[Hassi123]

its the one for aldehyde, the one for ketone is similar, ill try posting it if i get the time, i hope you get it though, as my phone camera sucks

 

[saudha]

thank you

Angular/Bent, 117 degrees. An example is SO2.

still, SO2 has a bond angle of 120 degrees (trigonal planar)..in our syllabus !
I guess so

SO2 is 104, its s03 which is 120. So2 has two bond pairs and two lone pairs making it a bent molecule like h20

hmm yes i guess its correct..

hmm confused..
