oh sorry i meant elimination **Halogenoalkanes undergo Elimination/Dehydration and Nucleophilic substitution. When adding KOH in ethanol (reflux), it forms alkene (elimination reaction) , not NaOH, with NaOH in water (reflux) it forms alcohol which is Nucleophilic substitution
hey noBut then it only shows single bonds in the ring...

Where are the double bonds inside the ring?

But they don't show it... so how do you know it has??hey no
the benzene ring has three double bonds within it
the electrons get removed frm the outer most shellhttp://studyguide.pk/Past Papers/CIE/International A And AS Level/9701 - Chemistry/9701_w07_qp_1.pdf
in question 4, why is it C and not D?
Oh i think i get you!View attachment 54511
that is how a benzene ring luks
u hve got me wrong :/But they don't show it... so how do you know it has??
Like this is a different question where they show the double bonds in one ring and then the other rings have the chiral centres marked
So if you consider the double bonds in this one in the rings you'd get the answer wrong

ahhh ok, thank you soo muchthe electrons get removed frm the outer most shell
nd looking at the graph we can say 2 electrons are removed frm the outer most shell bcaz u can see there is a huge difference between the third point nd 2nd point on the graph which means 3rd electron is removed frm a shell closer to the nucleus that is the 2nd last shell
so the outer shell has two electrons only nd this happens only in a grp 2 element
no problem just making sure that correct information is passedoh sorry i meant elimination **
thanks for correcting bro
nehaoscar sorry for my error....i hve been typing too much
yes ur rytOh i think i get you!
Is it that if the ring has a circle drawn inside it, then it's a benzene ring with 3 double bonds and if it doesn't have a circle it doesn't have double bonds unless specified??
most welcomeahhh ok, thank you soo much
Yayy! Thankyou!yes ur ryt
the circle is the ring itself
lolYayy! Thankyou!
Could you also please if possible look at some of the previous questions I have posted which have not been answered from the end of page 681 on this thread onwards?

Why not A?
Ketone is present in CH3CH2OCOCH3, secondary alcohol oxidise to form ketone with H+/K2Cr2O7 (Oxidation) , It's not esterification as carboxylic acid is not used.View attachment 54517
Why not C?
