MATHS QUESTION PAPER FOR CLASS 11
can someone please attach the annual exam maths paper of their school only if it is of a challenging level??
hydrocarbons
Write down the products of ozonolysis of 1, 2 - dimethylbenzene (o -xylene). How does the result support Kekules structure for benzene?
hydrocarbons
how to distinguish between but-1yne and but 2 yne
this is from hydrocarbons ncert 11th , so need answers without tollens reagent or any other 12th stuff...
Radial field due to ring
What and also how to easily derive the radial field due to a ring of radius R at a distance r from the axis of ring, (r<<R)? (slightly outside the ring)
iupac
2 methoxy pent-4ene or 4 methoxy pent2ene
dumb doubt but cant figure out whether ether>double bond or ether < double bond
online sources give diff answers...

SN1 or SN2
polar protic solvent ke respect mein SN1 or strong Nu- ke respect mein SN2, toh SN1 hoga ya SN2?

Henry Law
If we see this by temp, solubility of gas in liquid is inversely proportional to the temperature, so temp. : Delhi>Srinagar so solubility in : Delhi<Srinagar so acc to me soda bottle should loose its fizz faster in Delhi

Length of Normal Chord subtending Right Angle at Vertex
No idea on how to do this
coud only make out the figure nothing beyond that :p...

pnc doubt
A regular polygon of 10 sides is constructed. No. of ways 3 vertices be selected so that no two vertices are consecutive is.....
i understand this and but i tried using a diff method and it didnt come right...if i arrange the 7 gaps between 3 vertices ensuring theres always one in between 2 vertices i'll get x + y + z =4 and so i'll get 6c2 = 15...why isnt this approach correct?...

f-block, subjective question
"In what way are the observed oxidation states of the lanthanoids related to their electronic configuration?"
Chemical kinetics, factors affecting activation energy
My sample paper says activation energy is affected by:
* surface area of the reactants
* physical state
* temperature
* catalyst...
