1For qn 53, there are 5 isomers.
prop-2-en-1-ol
prop-1-en-2-ol
cyclopropanol
(Z)prop-1-en-1-ol
(E)prop-1-en-1-ol.
1In qn 36, i think we have to be given that "introduction of dielectric slab increases capacitance". Otherwise, the two statements are completely unrelated. So, i thought answer should be "B".
1doubts .
6) 3/2 is also correct no ?
48) hydrogenation can happen even with the other side no ? so diastereomers no ?

thanks.
21Q4 If the normal at the point P(θ) to the ellipse x2/14+y2/5=1 intersects it again at the point Q(2θ), then cosθ=
SUM1 PLZ FIND THE ERROR IN MY METHOD PLZZZZ......
@ IS ASSUMED AS θ
the 1st Eqn. is that of normal at point @.
If that wen produced meets the ellipse at 2@ we can apply eqn of chord joining two points @ & 2@ given by eqn 2.
but the Eqn. of chord is same as Eqn. of normal thus comparing Eqn 1 & 2
we get result 3......
then the value of cos@ that we get is sumwer around .47
PLZZZ HELP SPOT THE NOT IF NE!!!!!!!!!!1

11q9 equation of hyperbola is not given i think then how can it be solved
11then how can it be solved
in such cases shudnt marks be given to all those who attempt
9thanks bhaiyya realised my foibles
here is a revised list of my dbts
27) actually C is in series , none of options r right
41) option a is correct while solvin uve taken lenght L instead of L/2
49) i think this was a prev iit q and sol given was a cos of eq concept
55) shudnt ans be ab cos even a strong alc Koh rxn is feasible though slow
59) m-directing can also exclusively dactivte op pos wen it has +I,-R
62) can u explain why i dint understand;(
63) ans is d cos its less acidic due to hbonding pka walues are evidence
11im not getting q33 if D is at a greater potential current should flow from D to A rite??
please correct me if rong
1hey q17 i gav the correct ans which as 10 as shown but i was given -1 4 taht ,why?
