Dont you think 5th and 6th mein options are a bit weird? For instance there are only 6Cr-O bonds in dichromate and since all of them are equivalent in length both options b and c should be correct and also 6th wale mein what exactly is the wrong statement?

I'm pretty sure nitrogen dioxide ain't being released from an organic reaction

#

ncert is wack, man

frigid wave
#

Yeah

#

You are not getting NO2 from an amine

astral latch
#

oh wait nitrous acid is just HNO2 lmao

#

yeah you'll just get alcohol and nitrogen

#

(C) is wrong for 6th @empty berry

frigid wave
#

Yeah, it's the Liebermann nitroso test(?)

Hehe my bad

riyal

But 5 is c right?

empty berry

#

Because the Cr-O-Cr linkage is gonna be different length i reckon

#

Because it's not in resonance like the rest

astral latch
#

sorry why is Cr-O-Cr not just two other Cr-O bonds

empty berry
#

Cause there are six Cr-O bonds which are equivalent and the two bridging bonds are diff right?

frigid wave
astral latch
#

when they say "Cr-O" bonds i count the center bridge as 2 of them

#

am i not supposed to do that

empty berry
#

This is what my teacher made me write if this helps

frigid wave
#

I didn't see the options

empty berry

#

All are not equal

astral latch

#

Exactly 6 of them are equal

empty berry

#

hence why the answer is "6" and not "all"

#

Proof by Wikipedia

Here is the explanation of book

#

i think technically the center O can participate in resonance, but it just wont

#

because why would oxygen want a positive charge

empty berry
#

Yes

astral latch
#

also the Cr=O(+) is different from Cr=O

#

should i mark this as solved @empty berry ?

empty berry
#

I think yes thank you so much, ig it's just an error in book

astral latch
#

complete trolling
